Sadly, You may have a chop job for wiring b/c its an OBD0 motor and we don't know what OBD they used for injectors, dizzy, alternator, Intake Manifold.....lots of stuff. I am guessing its all OBD0 and someone just spliced a ton of plugs onto the EK engine harness.
I gotta ask....even though you would/should have stated....was there CEL when it was running?
