wiring harness...??

[R Dubya]

I am ashamed to admit this, but after 2 months of not having the engine in this car, I have lost my mental picture of the wiring harness at the starter.  I did something extrememly stupid and put the wrong wires on the starter motor, and when I tried to start the car I had a bit of an electrical fire down below the coils, from a reddish orange wire that I mistakenly attached to the starter.  I cannot, for the life of me, remember where that wire goes.  

I am thinking, obviously because it caught on fire and melted in half, (nothing else was damaged, Thank GOD :lol: ) that it was a ground.  It comes from the same harness as the left half of the ICM and splits near where the A/C compressor is.  I don't have a pic yet but will post one unless someone can clarify what I am talking about.  Could this be the ECM ground?  I don't remember where it was attached.  Thanks.
