92 MUSTANG; WILL THE HARNESS FOR THE COMPUTER UNDER THE DASH FOR A 4 CYLINDER,EXCEPT THE COMPUTER FROM A 91 5.0 LX. I AM SWITCHING MY 91 5.OLX INTO A 92 4 CYLINDER CONVERTIBLE.

 

Sure, the harness will physically connect but it wont be wired right. You'd have to switch a few wires around and then you would still need the injector harness from a 5.0 as the 4cylinder harness was obviously made with only four injector connections. Its easier just to use the 5.0 harness then trying to modify the one from the 4cylinder.
