Trans am GTA Lt1 swap help
I have put a -95 caprice LT1 9C1 engine in my -87 trans am GTA.
Engine runs greate but do not stop when i turn key off!
first i pulled battery and connector on the alternator.
Now i have noticed i can pull the pcm/ign fuse to kill the engine.
I have done something strange with wiering, someone hwo have any ide’s about this problem?

It sounds like one of the 12v ignition (key on) power wires to the pcm is run to batt(hot at all times).I put a link to the pcm wiring schematic.
