Resolved 1g wiring harness connectors ID

[agentorange313]

Hey Tuners,

I am about half way done with my wiring harness for my 1g.

I have a couple of connectors that i need help identifying. I have been using this link: 1Gb DSM 4G63 Turbo Wiring Harness Diagram for most of the connectors, but there are some that are discolors and hard to ID still. Not all the connectors are identified either.


I have 4 connectors that I need help with an identification:

Removed picture, found out it was the wiper connector.

4 I am pretty sure this is the Emmisions harness, but the wires are covered in the picture and wasnt sure if it was correct

There is also a wire that has been spliced to the ignition power transistor, I have no clue where it goes or its function:

2 appears to be either the thermo switch on the thermostat housing for the AC, or it could be the AC pressure switch that is on the ac tubing on the passenger side of the engine bay- its hard to say since both plugs are identical.
3 may be the plug for the dummy light in the brake reservoir.


The last plug that is spliced in is likely the plug for hooking up a tach when setting timing and idle.

Thanks for the help.

The connector in the 2nd picture is probably AC since you mentioned the other connector looks the same, they are actually wired together.

I think the last picture is of the Engine speed signal:

Where does this plug connector?

Can anyone else confirm that that the 3rd picture is of the brake reservoir?

The third picture looks to be the the plug that goes into the boost solenoid. Correct me if im wrong.

I dont think that is correct, I have already ID the boost control solenoid. If I am not mistaken the wires are red and yellow/orange.

Also i am assuming now that boost control solenoid and wastegate solenoid are the same

Connector number 2 is B-31 AC coolant temp switch.

Connector number 3 is A-12 Brake Fluid level.

Connector number 4 is A-13 EGR.

Last picture is connector A-56 engine speed.

Thanks a lot exactly what I needed.
Most appreciated.
