Ok so I want to clean up my engine harness and route it more under the dash behind the motor. I pulled it out and removed all the tape and rubber stuff from the entire thing. There is a rectangular 2-pin connector on the back side of the motor, I have no clue what it goes to. There is one on Marty's car as well, I can't figure it out. Can I remove this from the harness? Also there is a thick black wire with a cut end that doesn't go anywhere, in the small segment that goes toward the plugs under the dizzy and the reverse switch, any insights?
