Help identifying some wiring on a Galant VR4

[GST with PSI]

I'm attempting to repair my hacked up wiring harness since the previous owner thought it would be a good idea to convert all the factory connectors to spade connectors. I'm in the process of connecting the factory connectors back to the harness but I'm having trouble identifying a few wires. I'm working with the harness that contains the temp sensor connectors, and the O2 sensor plug. There are 6 wires total. When looking at the photo, just pay attention to everything before the crimp connectors (the actual factory wiring). I'm getting rid of the crimp connectors and soldering the factory plugs back in, so pay no attention to the wire colors after the crimp connector.

I have 6 wires total.

2 Green w/ black tracer
2 Yellow w/ green tracer
1 Blue w/ black tracer
1 Green w/ red tracer

The only one I have definitely identified is the Blue w/ black tracer. Can someone give me a sure answer on the other 5? Also are the 2 sets of identical colored wires interchangeable (meaning the 2 Green w/ black tracer and the 2 Yellow w/ green tracer)? As it was hooked up by the last guy, the the Green w/ red tracer and one of the Green w/ black tracer is going to the Coolant temp sender to the ECU. According to the diagram here (look at page 148) click, that is wrong, and it should not be hooked up there. Problem is, I can't find the 1 Green w/ red tracer anywhere in the schematic. Can someone take a look at their car and let me know what color wire goes where so I know indefinitely and don't have to redo this again? I wish I had another Galant to look at, as my 90 GST is totally different.


Just so I have it right for troubleshooting, the sensors as seen in the pic below are:
Top right sensor = Temperature sender to ECU
Bottom right = Temperature sender to dash gauge
Bottom Left = mysterious A/C sender (This is where the blue wire with the black tracer goes and is GVR4 specific?)

Again, as seen in the pic below:
Top sensor = A/C thermo switch
Middle left side = EGR vacuum switch
(again) Bottom left sensor = Temperature sender to ECU
(again) Bottom right sensor= Temperature sender to dash gauge

If someone could take a pic of the plugs on their GVR4 that would help A LOT! As long as I can figure out that wire goes to what, I'll be ok. Thanks in adbance for any help.

Can anyone chime in on this?

im kinda having same issue i don't know what color wires go to coolant temperature sensor as mine were cut by previous owner

You might find the answer some where here. Galant VR-4 Library - /docs, if you still have a hard time I can post some pics of my gvr4. Lmk

hey dsmkauai if you could take those pics it would be awesome , because my PS3 won't open your link on your previous post and trying to figure out wire is a pain

Ill try and take a look at my GVR4 and see if I can help...

Did this ever get resolved? I'm dealing with the same issue now.

Single pin front (connector B01): Coolant temp gauge unit: Yellow/green tracer

T-pin front: Coolant temp sensor (connector B02): Green/black (crossbar of T) and yellow/green (stem of T position)

Single pin rear: Coolant temp for A/c (connector B-22-4): Blue/black

Two pin on top of housing: Temp for a/c cutout (connector B-22): Green/red (from wire side, round side up it is the right wire) and green/black

The green/black should go to the ECU, and the green/red to the pressure switch and control unit.

What I ended up doing was use a meter to test continuity between the ECU, and wires that were still in question. To do this, unplug the yellow plugs at the ECU. Put one probe of the meter on the pin at the ECU plug, and the other on the wire in question. This way, you can correlate an ECU pin to the wire at the T-stat housing.
