pulled the wiring right out of my old ignition control module so I was hoping someone would have a pinout for a 98 gtp icm.

i ganked a new harness connector off a series 2 non-sc engine (same plug but possibly different colors on the wires). The original harness had the molex connectors pulled all the way out so no way to check against that.


I'm getting a check engine code for ignition control module voltage too high, and when I open the throttle I get nothing but stumbling.

any help is appreciated.

all the pinouts can be found there.

All I found from that link is about 1/3 of the pins (~A-F), a full pinout of the icm connector is what I need.

Anyone? The only one I don't know is a black with white stripe, position K.


:edit: I found it, it's a ground.
