Can anybody help me out here? I have done a Google search as well as searching here but I'm o. CF mobile and the results are not that great.

Trying to install NOS brand window switch.

I need to find an RPM/tach output wire to signal my window switch for nitrous.

OK, it starts at the PCM from Pin 10 (White wire) on the Red connector.

https://www.dropbox.com/s/s1qllv99u2...Views.pdf?dl=0

It travels from there to the engine fuse box and then into the car to the IPC.

Where do you want to pick it up?

Probably at the PCM. Finding it in the harness running inside the car would be harder in my opinion.

Doesn't the wheel and inner fender have to come off to access that?

Yes, but that is easier than trying to fish out the wire from inside the car. You might try to find it inside if you trace the Middle Fuse Box connector C2 harness to inside the car. However there are 3 wires that are White in that harness.

I'll try and help you anyway I can.

I was reading this one as well. I am just not understanding how to test for the correct wire.

Does anybody know if there is a wire that can be used by the coils?
