2nd gen Aftermarket Power Antenna Install

[vr4joe]

What's going on fellow DSMers

I did a very intense search on replacing the power antenna with an aftermarket unit and found a couple of threads but never really found a solution.
In this Resolved thread I found out which each wire is for but I'm having a hard time figuring out which wires I should tie into. I would like to combine some of these threads and built the ultimate solution with diagrams other than the confusing Mitsubishi wiring diagrams floating around on this forum.

My issue is the aftermarket motor I purchased (which came with no diagrams or directions) has only three wires. Black, Green and Red.
I'm assuming
Black = Ground
Green = (-)
Red = (+)

The stock Mitsubishi wiring harness (96-up) that connects to the OEM antenna has Six

Black w/ yellow stripe --- IGNITION
White w/ black stripe----- (-) GROUND
Red ------------------------- (+) B
Red w/ green stripe ------- ACCESSORIES
Blue w/ black stripe -------- ANTENNA


The aftermarket antenna unit has the motor within the casing, whereas the OEM antenna unit does not. The motor is located outside the unit casing which makes this installation slightly more difficult. I figured that I could connect the Red and Green wires from the new unit to the green and green/red wire from the factory wiring harness and be done with this wiring project, but it didn't work. I assumed the factory Green wire going to the motor was the negative and the Green/Red wire was the positive to feed the stock motor.

Please refer to the diagram I have created below. This is the new antenna motor with the OEM harness attached to it. The second photo is the old OEM unit with the two wires I speak of that lead to the factory antenna motor.

Could someone please tell me which wires from the factory wiring harness should I tie into to make this new unit work probably. As you can see I've already tried splicing into a couple of the wires into the factory unit as trial and error.

Anyone? Have I confused everyone?

 

[spyderdrifter]

I'd hook them up one way, and if it didn't work, swap them. If that doesn't work, use a multimeter to test which one on the factory harness side supplies the power.

 

[vr4joe]

Thanks for the help guys. I still haven't been able to work on the car since it's at my parent's house. I can't believe no one has bought this type of aftermarket antenna for their DSM. I don't have a problem using the multimeter, but it would save a lot of cutting and splicing wires performing the trial and error approach.

I deleted what was here because I GOOFED - see post 8.
Ignore what I said (quoted area) in post 6 also.

- BLACK to either ground or pin 6 (black) of antenna motor harness side connector (not the antenna relay).
- RED to pin 2 (black/white) of antenna motor harness side connector. This is ignition switch power. [It's actually black/white, not black/yellow (your yellow is a faded white).]
- GREEN to pin 4 (white/black) of antenna motor harness side connector. This is the control signal. Radio grounds it to operate the antenna (make go either up or down). Radio floats it (disconnects it) when not operating antenna.

OP, did this fix the problem? Id like to get my power antenna working again also

 

[vr4joe]

Thank you Luv2rallye. If you look at the two wires that i spliced ( black wire w/ white stripe and white wire with black stripe ) you can see I already tried that connection strategy.

I think I'm messing up with the ground. I attached the ground wire right to the car, which it looks like I'm suppose to do, considering it already came with a loop ground connector.

Not sure what I'm screwing up here? Am i suppose to just leave the old two stock green wires that went to the OEM motor disconnected?

98Spyder_GS - I wont be able to work on the car until the end of this month. ( Car is at my parents, and I'm trying to wrap up a few projects around my house ).

I'M SORRY I GOOFED in my post 5!
(I got mixed up with the wiring on a different car).

For your 3 wire power antenna try this:
- BLACK to either ground or pin 6 (black) of factory antenna harness side connector (not the antenna relay).
- RED to pin 1 (red/black) of factory antenna harness side connector. This is constant +12v power.
- GREEN to pin 4 (white/black) of factory antenna harness side connector. This is the antenna control signal from the radio. Radio keeps +12v on it when radio is on to keep the antenna up. (Sorry but with only a 3 wire antenna it may go up for just the CD too depending on the radio design).

Of course you'll have to connect your radio antenna wire output (usually blue but doesn't have to be) to the white/black up at the radio end.

Let me know if that works for ya.

 

[vr4joe]

OK guys. I finally had some time this weekend to do some work on the GSX. The correct connections are as follows.

Aftermarket Antenna

RED Connects to Red wire on factory harness ( content power )
GREEN Connects to Black wire w/ yellow stripe ( Ignition )
BLACK Grounded to car

These connections correctly make the antenna go up and down.

Now i'm having an issue with reception. I literally cannot get any channels and I believe Luv2rallye stated to connect the blue antenna wire to the black/white wire at the radio? Luv2rallye, can you explain this?

 

[luv2rallye]

Well you don't have a blue so you can ignore it. On some antennas there's a blue for "power antenna turn on" function for radios/antennas that support it. So the antenna will go up only when the radio tells it to (eg. not when CD is playing or not when key is in ON or ACC position but radio is off). Do you have an aftermarket radio? Also does your antenna go up when key is in ACC with radio on (or even with radio off?)?

For reception did you connect the antenna coax cable? Is the coax cable shield grounded at both ends? I assume the radio turns on and you tryed to manually tune to a known station.

Well I'm glad you got the antenna wiring figured out. I've found that not all aftermarket antennas and aftermarket radios use the same wiring (even when they claim they do or claim they adhere to a standard). Your "black wire w/ yellow stripe" is probably just a faded white stripe that looks yellow which is actually then shown in the factory wiring as the black/white wire from the ignition. If so, the antenna probably goes up whenever the key is ON whether the radio is on or not. And it doesn't work in the ACC position. Does this happen?

 

[vr4joe]

Yeah, it works in the ON position and when i turn the car off, it goes back down. The antenna coax cable is plugged in correctly and still does not work. I turned the stock radio to a bunch of known local stations and I get nothing but static. I cant even hear any music... just static. Is there a way to trouble shoot this? I pulled the factory radio out so see maybe the antenna cable become loose behind the radio, but the connection was good.

I'm thinking if I connect the aftermarket motor green wire to the car harness green wire with red stripe (acc) it'll go up when the Key is in the ACC mode.

Another question. What is the Antenna wire for within the stock harness (the blue wire with black stripe) ?? you can see it in the pictures i attached in the first post. Is this a ground for the antenna coax? I'm so confused why i have no reception.

OK. So I tied into the green wire into the blue w black stripe wire ( Antenna ) and it worked correctly. The antenna goes up while the key is in ACC mode.

Correct wiring!

Red ties into Red wire (power)
Green ties into Blue w/ black stripe (Antenna Power)
Black gets grounded to the car.

Now I still can't figure out the reception issue. I'm now thinking its the stock radio that's the issue. I was thinking that the factory antenna coax that runs through from the back of the radio to the antenna had been crimped or ground somewhere. instead of pulling all the trim out. I ran the aftermarket antenna coax directly to the back of the stock unit and still no luck.

I wish I had an extra DSM radio lying so I could test my theory. What do you guys think? Am I missing something?

 

[luv2rallye]

The Blue w/ black stripe must be the ignition key ON/ACC power wire. On my 99 factory diagrams it shows it as an all blue wire but apparantly that's it.
[I was actually going to suggest using it if the black/white didn't work out properly. A problem with the factory diagrams is they only show the antenna motor/relay as an assembly and the relay as just a box inside it. They don't show wire colors between the harness and the antenna motor relay or motor inside this assembly. So not knowing what's inside that relay (which shows 7 connections to it) makes it somewhat a guessing game when your replacing the entire thing with a 3 wire antenna.]

For the lack of reception issue I'm at a loss. You have the Infinity factory radio correct? On some years the radio case must be connected to the frame to work properly so you might try touching a ground wire to the case to see if any difference. The Infinity radio also has 2 antenna coax inputs. The larger one is for the mast antenna and the smaller for the hatch glass antenna. I don't know why either wouldn't work but it's a thought. Maybe temporarily just try sticking an unconnected 3' wire into the larger input to see if you hear any difference (thereby verifying if the radio works and your coax isn't broken).

 

[vr4joe]

Thank you again Love2Rallye for your input. You've been a great help on this subject!

Regarding the diagram you attached in the last post. The plug that is labeled hatch glass antenna might be something else. Both are plugged into my stock unit and when I pulled that one out the radio lost power. I think it's something else because I got 12volts from that plug.

Are you sure you're talking about the radio hatch glass antenna plug (on the radio back panel itself) shown in my attached picture? Because that is a antenna coax connector. And on my 99 GST (my Infinity radio has both cassette and CD) I know for a fact that it goes to the wire antenna in the hatchback glass (not all models have that antenna however). If you measured at the hatch glass you may be confused with another connector there which is the rear hatch window electric defogger which is +12v. The hatch window glass (on my GST) has wires in it for both a (secondary) radio antenna and a defogger. If you follow those wires carefully you'll see they don't connect. But again not all models have the hatch glass antenna.
