Eclipse to Talon Tail Light Wiring ConversionFor the longest time, I've wanted to convert my Eclipse's tail light wiring to function like the Talon's where the brake and blinker lights are completely separate from each other. If you do this with a hard top Eclipse, it could be as simple as swapping a section of the harness, and the blinker relay. However, for the Spyder, that isn't possible (without major splicing of the two different harnesses). This setup can still be done, as many members on this forum have done it, but I haven't seen any write-ups. With help from 97eclipseNT, I have completed the wiring modification, and the tail lights operate the way I want them to. I give him credit for the info I'm providing, but I'm just the...
Little break down on why and how i got to this stage. My cars in the UK so we are similer to EU rules and regs so we have only Amber indicators in the rear but when the car was imported so many years ago they rewired some bits took some wires out for the rear and it needed tidying up.So I lost the 4 rear bulbs that are USA regs for brake and indicator, the front wings get side markers and the bumper marker was an indicator. When i recently redid the wiring to get rid of old wires and clean it up i ditched a few bulbs as i dont need them no more and this caused me some issues even before LED bulbs! I bought some LED bulbs that had build in resisters but clearly were not enough for the system and not able to compensate for it.The fix...
Hello fellow DSM folks. I wanted to post this thread to show how to wire the horn with an aftermarket steering wheel without getting the wires all tangled up inside the hub. Hope this helps other people out with the photos and video I took!Tools needed : -18 AWG stranded Wire -Heat Shrink (optional) -Heat Gun (optional) -Wire strippers & crimpers or solder gun (whatever you prefer) -Butt Connectors -Ring Terminals -Female pin terminal (get the ones with a rubber protection on it, so if it touches anything the horn won’t go off) -Hose clamp1. Remove the steering wheel (optional) (find it easier with it off since it’s not in the way)2. Remove the steering column. (2 or 3 screws underneath the column.)3. Find your horn connector...
This article is designed to help 2g owners identify all the plugs in the engine bay.The photos and wire colors were based off of a 1999 Eclipse GSX, so other years and models may vary in location and wire color.I would like to give a HUGE thanks to turbosax2 for helping with the photography and the documentation for the article!!The way the tech article will be set up will be as follows:This post will have the master list of all the connectors. Each connector will then have it's own separate post below which will contain a little description and a few pictures and diagrams. The first picture will be an overview shot to show the general location of the plug. The plug will be circled in green. The next picture will show the...
This article is meant to serve as a general guide to get the horn to work with an Nrg short hub or aftermarket steering wheel. Credit goes to this particular article for the idea of using a hose clamp: https://www.dsmtuners.com/threads/how-to-get-your-horn-working-with-an-aftermarket-steering-wheel-using-a-clamp.373149/ Also take note of the picture from this article to see a hacksaw blade used instead of a hose clamp: https://www.dsmtuners.com/threads/cruise-control-switch-relocation-and-horn-connection-with-aftermarket-steering-wheel.222394/ ********Note: I will not be going over srs light or how to maintain airbags Useful Videos: -For disassembly//assembly of nrg setup wheel-To understand the general concept of how the horn works...
Not enough space in your favorite car's engine bay? Do you really not like that eye-sore of a battery next to your 4g63? Not wanting to add hundreds of dollars in breakers and inline fuses?Well utilizing the stock fused components you still can toss your battery in the trunk or behind the passenger seat.What you'll need:-25 dollar 4 terminal distribution busbar with plastic cover (TSIAWD666 uses one also) ~readily available on ebay-2 Gauge wire for extending the positive post connection (7 to 8 feet to reach behind seat, roughly double it to place the battery in the trunk) ~[2 dollars a foot] I went to Advance Auto for all the wires-4 Gauge wire to ground the negative (2 gauge works as well but not necessary) ~[Most likely...
We'll start this with the standard disclaimer: This is a modification made to our car. The following article shows you how this was done. You alone take full responsibility for any modification you make to your own car.After having many cars pull out in front of us, seemingly not seeing our low-slung DSM, I wanted to have some lights to help us be seen. When I remembered, I would turn on the parking lights, but often I would forget, until some moron pulled a stupid move.I'm not generally a fan of Daytime Running Lights (DRL), but with all the work that goes into our cars, an insurance check and a body shop are not going to get us our cars back using today's Book values. So, I decided that the coolest I could make DRLs look...
The 94-96 cars (correct me if I'm mistaken) have a separate cam angle sensor and crank sensor. Other years have them both in one unit on the passenger side of the head.Here is where the CAS is located on these cars:Closeup:You'll first have to make a wiring harness to connect the 1gCAS to the cam angle sensor and crank sensor connector. (Link on how to make this harness: RRE Instructions) step 1 is to cut the wiring harnesses for both. Cut them so you have as much wiring as possible to work with as you have to route the wiring around the back of the motor. Here's where I cut the cam sensor:This is what the connector looks like for the cam angle sensor:Here's the whole pigtail I cut off.If you're...
Hey I had to change my O2 sensor so i figured i would make a tech for it while i was doing it.:)You might need to change you O2 sensor if you fouled your old one or just if you want to replace a old crusty one with a fancy new one.tools you might be needing: O2 sensor socket Ratchet with extension Torque wrench anti-seize compound(local car parts store or comes with sensor) New O2 sensor, wires, connector (the o2 sensor im using is the Denso: First time fit, it seems to be the best no reason why you shouldnt get this one, it can take leaded gas and has extra water protection among other things, all for $94 shipped) i got mine from machVthis is what your looking for on the car
I started a thread on an electrical issue i was having. And came across lots of 2g 95-96, 97-99 wiring information. But it was across many threads and websites. so i would like to put it all in one place for everybody!This is what i have so far!!!I would like this thread to contain as much electrical as possible for the 2g dsm both 95-96, 97-99 eclipse gst, gsxplease add any and all wiring information or labeled diagrams/pictures you can to this post. if you have a better quality image then someone else please add to the thread. Thanks!-how to post:year of 2g (ex. 95-96, 97-99) short description of what your posting automatic/manual transmission (if known)95-96 2g factory electrical service manual97-99 2g turbo factory...
In this thread Ill show you how to install a vac pump. The reason you would do this is to help launches when your brakes cant hold you back. While sitting at the line with boost, there is no vacuum going to the booster. This is mainly for people with a auto trans.You will need wire, wire strippers, crimpers, relay, hose, check valve, and the pump. You need find where you want to mount your pump. This is the pump I got.You need to remove the hose at the brake booster. You need to put a T in this line. On the remaining two ports, one goes to the booster and the other is going to the pump. In the line going to the pump is where you need a check valve put in place. Remember the pump is providing vacuum.Next you need to cut...
The 2g's have alot of problems with the horn buttons not working. I took a few pictures and figured I'd put put something in print to go with it.First and foremost ALWAYS check your fuses first. Check both the fuse block located just above the left foot area inside the car and check the power distribution center (fuse block under hood) for blown fuses.I prefer to check most electrical problems at opposite ends first and then work my way towards the middle of the circuit. The horn under the left front head light (on 99RS models at least) and the switches at the steering wheel are the ends of the system. It's easier to get to the horn switches themselves rather than the horn.So the first thing you'll want to do is...
Original information found here: http://www.angelfire.com/fl5/import/germantail.htmlOne of the steps found there was not needed, and some of the instructions were a little confusing so I modified it a bit while everything is still fresh in my mind.Parts needed: 2 8-ohm, 20-watt resistors from Radio Shack(Part #: 271-120) Some spare wire, you may want to pick up a roll of speaker wire at Radio Shack Wire cutters and strippers 10mm deep socket Flathead and Philipshead screwdriversNow, on to the fun:The amber-cornered European/Japanese taillights will work with the American version of the 2G Eclipse as long as you make some modifications to the wiring. Hopefully you have access to instructions on removing your...
I'm going to show you how to hard-wire your SD kit and Flex Fuel sensors instead of using an adapter harness for those either redoing their engine harness or you simply don't have the funds for the adapter harness.There was very little information on MAF wiring that I could find but maybe I wasn't using the right keywords.. Regardless, here's credit to this thread for having what I needed: https://www.dsmtuners.com/threads/2g-maft-wiring-diagram-very-simple.442096/ After reviewing that thread, I then traced all the MAF wires across my harness to confirm where they went. There is a diagram that includes the ECU pin #'s a few pictures down if you're making a new harness. My car is a 98 GSX- your wire colors may vary but the positions of...
INTRODUCTION I notice there are not that many install guides for installing the Apexi Super AFC, usually its because the links are so old you can't find them. So I decided to write one up with pictures and good diagrams. I'm doing this write up for the 2G turbo's, I am not sure if the 1G or any others car is the same. I do know for sure that that the 2GNT install is totally different as the ECU is in the engine bay and it uses a MAP sensor. I also did this with the first SAFC, for the AFC, SAFCII, or SAFC NEO I am not sure if it is exactly the same. Another note is that this install guide will cover basic installation/wiring and setup. For tuning info you'd best look at the many other guides on tuners.INSTALL TIME This took me...
I have fought with DSM alternators for years and I'm sick of the $120+ cost of replacing a weak 65amp stock unit. There are rewound units that put out 105 and 135amps but at a cost of $175-$250 I say no thank you. If you have a few basic tools a a little bit of time here is your answer.Tools needed:basic hand tools: wrenchs and sockets small grinder or dremel soldering ironParts needed:Saturn Alternator from a 93-99 Saturn 1.9L dohc ( 1996 Saturn SC2 dohc )I did the mock-up on a spare motor and have also done this on my car. It took about 30 minutes using a dremel.The benefit is a more powerful and CHEAPER alternator.Saturn, meet Mitsubishi:The alternator needs to be clearanced to allow it to rotate...
We've all seen good and bad attempts to light the center taillight sections on 2Gs. Although they look good when finished, most of us don't have the time or skills to hand-build led boards.Here's how we lit the center section of our 2G Spyder for $75.Disclaimer: This documents how we upgraded our taillight. You are responsible for your own modifications, and any results that happen. You will have to remove some interior body panels to access the center section attachment bolts, and to access the wiring harness. We did not use voltage regulators in this application, which can protect the leds from over or under voltage. You may wish to include those if you do this mod.Disassembling the center section is covered in other...
So I recently had my nearly new 17 month old oem 75 amp alternator go funny on me and it was time for this GALANT swap so I ordered a unit from the UK only to find out that the UK Galant is different then the US Galant!Im doing this because I could not find a part number to work with to help me search and it WILL save time in the future for others! so this should help people when they need to do this swap!this here is a UK Galant alternator matched down to the correct year and from the same engine 4g63 vr4 but this is 100 amps and I even tried the 90 amp 2.4 unit aswell but that was the same style aswell,this is the link Mitsubishi Galant VI | 100 Amp ALTERNATOR | 2.0 16V (A1939) - The Starter Motor & Alternator Company...
This is a write up on how to wire in a AEM 3.5bar MAP sensor in a 2g and log it using dsmlink V3. Since V3 is installed on your car its possible to remove your MDP (manifold differential pressure) sensor and in its place wire in a MAP sensor to log actual boost.If your still running the 2g intake manifold you'll also need to get the RRE MDP/MAP sensor adapter, which will let you mount the MAP sensor in place of the MDP. It can be purchased here --> RRE 2g MDP/MAP sensor adapter and to order it you need to call them, their online ordering system sucks but they do answer their phones.Heres what the RRE MDP/MAP sensor adapter looks like installed on a 2g intake manifold with a AEM MAP sensor mounted to it.With that being...
Okay here is my understanding, and what worked for me.The gear selector is still connected to the neutral saftey switch (grey thing on left) Their is no modification needed for that.From the NSS, i will solder the diodes directly to the new wires going directly to the solenoids in the transmission in the order the picture shows. In doing so i will add 2 wires in the cab for a switch to activate 4th gear, which will only work if the selector is already in 3rd.also my 2g wire colors are different, from the NSS on the 1g the colors i have are.1.big red. blue stripe -not needed 2.big black. white stripe - not needed 3.yellow. red stripe -goes to solenoids 4.yellow - goes to solenoids 5.yellow. black stripe - goes...
So I decided to do this mod the other day and I followed the directions from vfaq: 2G Fog Lights with Parking LightsHowever, the instructions were a bit sketchy as far as pictures and clear instructions. I did get it to work, but didn't like the setup, so I went about altering the mod myself.Like the original states, get an in-line fuse holder and put male spade connectors on each end. Then pull the fog light fuse out, and put it in the holder. Then pull your tail light fuse (left one in the picture) and put the spade connector in with the fuse. Then link the in-line fuse back to the power side of the fog light fuse location.After that's done, you're finished. The fog lights turn on with your parking lights. They still...
Ok so recently I got like 4 questions asked my direction on how to relocate the master fuse box panel from under the hood and bring it inside to the glove box. Well, first and foremost, I have no pictures, I did this trick almost 2years ago so im also writing out of memory.The other two very important things you do at this time (if you havent already done this) is one, you must relocate the battery to the trunk. There is several write ups on how to do this correctly, im gonna make it a douple point to repeat a few key items that are a must on a batt relocation. 1st, mount the battery with an actuall tie down box not ghetto style, 2nd, MUST HAVE 150amp fuse/breaker, 3rd, run a 4awg wire from the negative battery post the whole length...
So the Spidey write up was missing parts to get your signals to work properly. Most people who attempted the wiring came out with hyper blink. I have resolved this issue and also provided pictures. Lets get to it!Tools: Two 8-Ohm 20 what resistors Radio Shack PN: 271-0120 Solder Soldering iron Wire strippers/cutters Electrical tape 20' of Auto wire 10mm deep socket Regular screwdriver Phillips Screwdriver Volt Meter Awl/small pointy objectHopefully you have access to instructions on removing your taillights, but in case you don't, I've included a brief description of the tools and process. A 10mm deep socket will come in handy here. Remove the two panels for bulb access. Also take out the center section of the interior section of...
Continued from: http://www.dsmtuners.com/forums/articles-exterior-interior/452730-auto-dimming-mirror-conversion-part-1-a.htmlAuto-dimming mirror conversion for 2G DSMs: Part 2: Wiring the UnitTonight I finally started working on the wiring for my auto-dim rear view mirror. I've been itching to do this for the past couple days, but kept getting distracted by other things. But it is now figured out and is fully functional.So let's get started: I searched on a website known as ShopKey5 for the 300M auto-dim mirror wire schematic and came up with this diagram, which I took pics of and cropped them together.Don't be intimidated with the diagram though. You're only going to be using 2 wires; the Black w/LT green...
