Hello everyone, This is my first post. I was directed to this site from an "old Chevy site". I've read several post and think you guys can help me with my problem.

My question is, I own a sandrail. I have installed the 2.8 V6 from a 1989 pontiac grand prix on the sandrail. When i purchased the engine, they sold me the underhood wiring loom, computer(ECM), and fuse/relay box. I'm now ready to install the wiring on the sandrail. What wires can i get rid of? I know i don't need the AC wires. Also, where does the ECM get it's power. If anyone can help, i would appreciated it.
