Hey this is my first post here and I need a little help. I have an supposed 89 camaro (i believe it was a v6 they tried to v8 swap.) with the wiring on the driver side almost destroyed or mangled. The other harness is completely gone. I was trying to see if you guys could tell me if there is a main ground in the harness I have and will the fuel pump work with the computer or harness? Thanks in advance!

 

You need a manual with wiring diagrams. Take pics and post them up for better help. Yes there's gonna be multiple grounds but without knowing what you're working with it's all just word salads
