I'm in the process of swapping to a different ECM.
I'm looking for a diagram of the harness that the Fiero Factory used in their swap.
I already have the Cadillac service manuals, but I'd like to know the specific tweaks/changes the FF made before I tear into the harness.
If nothing else, I'd like to be able to put it back to original if my grand experiment doesn't work, for whatever reason.
Any help will be appreciated.
