Which wire is the ESP wire going into the PCM??

EDIT: This is for a 94 LT1 A4 Trans Am.

What is "ESP"?

I think it might be a trick question. If you had ESP, you would already know the answer.

The ESP wire is the wire that sends signals from the PCM to the coil I believe.

On the 3rd Gens, there was an Electronic Spark Timing (EST) circuit, involving the signal from the PCM, but in the LT1's they changed it to the Ignition Control Circuit.

The Ignition Control wire runs from PCM terminal A13, to the IC Module terminal B, and is white.

My psychic advisor told me there would be days like this.

Which set of wires coming out of the PCM would those be? Part of the grey, black, blue, or red group?

Look near the bottom of the schematics section of my Tech Page. It will show you all the wiring from the PCM.

I consulted with mister cleo (shoebox) and he said look on his web site
