im on the formula sae team at my university and we used to use the duetsch brand of connectors, but now we use the "cannon" style as you guys call em. theyre both pretty good, but the cannons are easier to connect / disconnect and should seal just as good. at the ECU box we use the amphenol and then all the stuff on the harness is cannon. works out quite nice.

oh and to "bundle" the wires together or whatever we use this expensive heat-shrink sorta stuff meant specifically for harnesses. not sure what its called
 
Received, just trying to now get the car shipped so the fitting can begin, still needing to get the oil and coolant system worked out and then it's a matter of wiring harness modification and re-installation.

Looks sick bro! Wish you could have came down before you left the U.S.. would have been nice to compare builds a bit and had a lil fun too!!

keep up the great progress and look forward to seeing her all finished! LOL

I'll be sure to let you know when I'm back in town, assuming my car is still there I'll be sure to make it a priority to stop by as well.:hellyeah:

Oh just so you guys have an idea of what site I'll be using for the connectors, knitted mesh, and heat shrink... go here and you'll find exactly what you need, and their customer service is great!
 
Hey guys I'm back haha.. And this is a great thread to return to. Great build
 
Sick build sir. Showed me a few things I hadn't considered yet on my own build. Also you may have stated it and I just missed it but what type of paint/powder coat did you use for your block? Mine was painted some NEON lime green affair and well needless to say it's gotta go and as soon as the block is out and disassembled that's first on the list.

Welcome back, thanks for the support. :thumb: Good things are to come in the near future - should keep an eye out. ;)

Thank you! As for the powder coat it was done in flat black, I can't find the listing he gave me to chose from (over 100 colours) but it was a powder coat. Came out really nice too, wasn't my work (as stated) but the guy who did it for me took so much pride into the job he felt as if he were building the car himself. I may have created a DSMer... LOL:hellyeah:


New stuff:

The harness for the ignition is getting an upgrade/modification, my Deutsch connectors, mesh, and heat shrink have all shipped! Going to change that and post pictures once completed. Near the end of December I should have my stuff ordered for the engine harness... that one will be a bit more expensive but I assure it will awesome once completed as well.
 
Im sure it will be Im excited I want to do so much to my dsm but gotta wait for a some other things to come into play, especially the engine bay and wiring.
 
Awesome build. Great motivation to get mine together.
 
Merry Christmas, or Happy Holidays, everyone! Rikka finally got part of her cannon plugs in so that's in work - will post pictures once it's completed. Will be getting the engine harness connectors and wiring on order after the holiday season.

Hope everyone has a joyous day! Don't forget to wish your DSM a Merry Christmas as well, especially if they're out in the cold.
 
Happy holidays to you as well bro! Build is looking nice!

I got almost all my goodies in to finish my setup as well, just waiting on my SS ABS removal lines from STM and a 3" vband o2 housing... other than that im about to send my trans to metro trans, tcase to devo 2ning for a 300m conversion 3.5" DSS drive shaft.

Cant wait to compare builds side by side! It ought to be real fun, esp with the same power goals :thumb:
 
So while in the UK still my friends at their auto shop figured out/proved that I wasn't hallucinating when I went into that barrier on I-70...

My rear differential seems to have something either wrong in the gearing or it sheered something off and is now locking up even at 30 mph speeds. What I don't get is it was geared correctly for the manual transmission (BFH) whereas my original differential wasn't (JFH) but then again it may have had the cover swapped but I can't believe that one either (but could happen).

Anyways, they're going to try and get it to work properly again, I'm in hopes that the transmission wasn't damaged by this as it set me back a pretty penny. After fixing that they plan to help me finish the fueling system as she runs out of steam after about 4k rpm (stock fuel pump) and floods the engine with a Walbro 255HP in it but on the stock regulator, which is being replaced by a Fuelab FPR that has a -8AN feed and -6AN return (feed/return at the rail is -8AN). I know that fuel feed is a bit big but I got it from Keri (MK Motorsports) at a great price, just needs a longer fuel line as it would seem the GST it was on doesn't properly fit a GSX. :ohdamn:

So yeah, will keep you guys posted on her status.
 
Well in latest news, the snow in Missouri is making it difficult for my friends (auto shop) to do the minor repairs needed to get her back on the road. As for recently purchased mods I'm going towards a solid mount setup, picked up some 1G inserts but they should fit snugly inside my 2G mounts. Will post pictures once installed.

lets you know exactly a leak is coming from way easierROFL
 
Finished the ignition harness, took long enough - will have pictures posted once I find the wall adapter for my camera... still also needing to wrap the wire loom to look neater. I've also begun work on the engine harness, currently in the planning phase so I have all the right wires and connectors needed to complete the project successfully (considering this is my "second" harness), this one is looking to be a bit more complicated and mainly because I had forgotten about the MPI relay located in the centre console. But that's all been resolved just need to make the wiring diagram so that all mistakes are ironed out prior to building - more than likely once I'm done I'll make a write-up that is picture in-depth so everyone will have all questions answered (this one is going to get nasty).

The finished product, just need to snip a few strings and then burn the edges (nylon) to prevent fraying.

The below harness is a very ROUGH schematic for what the engine harness will be wired to, similar to the ignition above it too will be mil-spec. With that being said and the ECU being converted to an AEM EMS Series II (for better control of the coils) I'm having to re-pin and relocate some of the pins and create my own harness. For now I'm doing 1/2 of the "control harness" due to the car not being with me at the moment - basically the half inside the car. Pictures to be posted during build and after completion. Keep posted!

That is some of the best wiring i've seen. i wish i wasn't a poor college student so i could own a DSM and do stuff like this! Anyways, keep up the great stuff man.
 
Thanks! I'm sure if you find the right dealers and whatnot you'd be able to make these too, luckily most of the tools needed (crimping tools, solder irons, etc) are available at my job so it makes it A LOT easier/cheaper.

Anyways, here is the other half of the harness, the sensor grounds aren't going to be split like that as they will be divided respectfully to what size pin is located in that spot. (Pins not labeled yet)

This is a very nice schematic and build you have going! Do you mind sharing the guage wire you are using as well? also how do you determine what guage wire to use where?

I plan, once I've completed it, to do a proper tech write-up to the forum (a lot of the others are vague - IMO). But to answer you questions there are two sizes that are used on the ECU connections: 18ga and 16ga. Looking at the connectors I'm sure you can figure out which ones are which. I've actually changed the second schematic because I left out something (posted below - power to sensors/fuel injectors), the larger and thicker wire may extend up to 14ga to 12ga just to ensure current capabilities.

If you're looking at the wiring harness I've created recently, the ignition coil (AEM Smart Coils) harness, the power and grounds are 12ga through the harness itself and then become 16ga at the connections, the remaining lines are all 16ga; green, and grey are tapped into one line and the power and grounds are paired due to current capabilities.

To determine wire gauge you should know the amount of amperage that most wire can flow, for the most part if you use the electrical FSM it'll tell you in mm^2 so just convert and stay with the stock wire size, even with my AEM coils they didn't need too much of an upgrade other than the power/ground wires for safety purposes.

Go to http://evoecu.logic.net/wiki/Plugs,_Pins,_and_Connectors and you'll find the connector part numbers then go to http://uk.mouser.com/ and type in the part number (they have a US site too), they should have all the pins you need, you can reuse your connectors as required. As for the connector used on the built harness I went to www.wirecare.com to get what I needed, and they have a lot (Mouser has much more and mil-spec).

Oh, definitely not, that 3" V-band is for a bottom mount manifold. I had bought this a while back with intentions of using it with the FP3065 I originally had but after I had sold that turbo to go to a GT4088R I never got around to selling it, nah I've got a top mount manifold with a different 3" v-band; the build is still going on (don't worry ;)).
 
So I'm caught between a rock and a hard place... upon creating the schematics for the control harness I missed the control to front chassis combination which houses the power for the MFI relay, radiator fan control/power, and A/C compressor control/power as well; I'm getting rid of it since my A/C is gone already and I plan on redoing the rad fans anyways with a different type of setup. Anyways, with that being said here's my "predicament." Also note that the fuel pumps will have their own relays that will be mounted relatively close to their respective locations and the battery (being relocated to rear) - the ignition signal will be routed to still trigger them just not at the MFI relay. Once I've figured this out I'll start the build of the harness but this is currently the problem child... but the two modified setups would work perfect for the most part as they either disable half or split the power among two relays.

Stock Setup of MFI Connection (95 Harness):
Pin 1 - R/B (+12v Constant)
Pin 2 - B/R (ECU +12v Supply - divided into pins 12 and 25)
Pin 3 - R (Engine Sensors +12v Supply)
Pin 4 - B/BL (Fuel Pump +12v Supply)
Pin 5 - R/B (+12v Constant)
Pin 6 - B/W (SW Ignition +12v for Fuel Pump)
Pin 7 - BL/LG (ECU Control - MFI Relay)
Pin 8 - W/R (ECU Control - Fuel Relay)

Modified Setup #1 (Divides Relays to Power ECU and Engine Sensors Separately)
Pin 1 - R/B (+12v Constant)
Pin 2 - B/R (Pin 12 @ ECU)
Pin 3 - R (Pin 25 @ ECU)
Pin 4 - B/BL (Engine Sensors)
Pin 5 - R/B (+12v Constant)
Pin 6 - B/W (+12v Constant)
Pin 7 - BL/LG (ECU Control - MFI Relay)
Pin 8 - W/R (ECU Control - MFI Relay)

Modified Setup #2 (Uses stock system but removes fuel relay usage)
Pin 1 - R/B (+12v Constant)
Pin 2 - B/R (ECU +12v Supply - divided into pins 12 and 25)
Pin 3 - R (Engine Sensors +12v Supply)
Pin 4 - Not Used
Pin 5 - R/B (+12v Constant)
Pin 6 - Not Used
Pin 7 - BL/LG (ECU Control - MFI Relay)
Pin 8 - Not Used
