Mopar crate engine harness

I'm also using a custom vehicle harness along with a crate engine harness / ECU system. I'm going to not run the custom system wires for fuel pump and fans. This, I believe is best, so the ECU can control the fans (based on engine temp input) and I'm pretty sure that if you run too low on oil pressure, the ECU will cut off fuel. That's my plan. I'll be verifying this further as I start to wire up my car, but just thinking ahead for now.
