Title: Wire Harness Question
Post by: 83TB on September 03, 2012, 01:58:21 AM
I have a 83 thunderbird V8 car.  I am looking for a 90-93 mustang 5.0, 5speed drive train for the car.  I have read that I will need the computer and wiring harness from the Mustang.  Is that all?  I guess I will mount computer somewhere and just give it power and plug in the harness from the engine compartment to it?  The original harness I just tuck away somewhere?  The interior harness and wiring I don't have to touch?  Any other infor would be great, Thanks for help!

You will need to make your dash work some how like the gauges.

The factory gauges in about any '80-'90 vehicle could care less about the computer that operates the engine... Gauges are operated by senders that would need to match the car not engine, just a matter of replacing with the ones from original engine.. Basically a total NON-issue...

You'll need to be sure you have the fuel pump wiring and relay, plus you'll need to install a higher output pump in the tank... If it also has a external pump, it can be removed...

There will be one wire that feeds the ECM relay(red with green stripe if I remember correctly, also same as battery side of coil), as long as it has switched 12V and all grounds are in place the computer system will operate...
