Year and model of the car, please. You could be driving a chevy for all we know. . Makes it hard to troubleshoot when we don't know what you have.

Therefore, no clue as to which wiring diagram you need. The wiring changed several times between 79 & 95.

That's why it is a good idea to use the sig under the user control panel (User CP) option. It allows you to post your car year & mods, which help greatly when troubleshooting things. No, it is not there for us to snoop and see any "Secrets" you have hidden away under the hood. Be a good stangnetter and update you sig for future reference & don't keep us guessing.

The odds are that the main ECC (computer) relay is the problem. Sorry, but I don't have a wiring diagram for any stock Mustangs eariler than 86.

Is the an EFI swap car with an injector for each cylinder or a CFI with one injector mounted on the throttle body? All the Mustangs that I know about prior to 85 were carb cars.

Go back an shoot ALL the affected wiring. Chances are, you have a stray ground somewhere. Likely a wire that you didn't see where the insulation was burned through.

The standard location for the computer in 86-93 cars was inside the passger kick panel. That would be the first place I would look.

Unfortunately is it probably on top of the computer. Removing the driver's side dash speaker in th 87-93 models helps. Since I haven't seen what the interior of an 84 Mustang looks like, it may not may not work for it.
