I am doing the EFI swap in my 64 1/2 Mustang. I plan on going with a 89+ motor because of mass air. Does anyone have any information on modifying the harness to fit my classic mustang. Any information or diagrams would be greatly appreciated.

 

You do not have to use the stock harness you can go to painless which is a aftermarket wiring company and they sell nice kits to do this.

Here is an engine harness for that setup.
