I have a 260Z and a '82 280ZXT engine to put in it. I have the computer, engine harness, fuel pump, heat shields, air flow meter, ignition coil, and all the other stuff. I have two questions. How do I wire the EFI harness, fuel pump, and fuel pump relay to the 260Z harness and do I need the 280ZXT ignition swith and ignition relay? Please help!
