Having trouble with the wiring harness for my 302. When I purchased this engine the harness was cut but all plugs are connected and so I am trying to use my plug from my 300 i6 and solder it with the old harness not sure but there are a lot of the same colors and they go to the same places I'm just not sure bc I have two or three wires without mates and have doubled or tripled some colors is this correct or have I fallen off my rocker again? I need some advice and I need my truck running please?
