Re: engine swap will the wiring need to be swaped too Reply #1 – April 24, 2005, 08:01:44 PM If you have a '88 SEFI 3.8 at the minium you will need a '87-'88 HO 5.0 Mustang ECU(EEC) and the wiring harness' back to the EEC from a '88 5.0 Bird/Coug. A '86 or '87 can be used but the connectors are slightly different. IF you are going to have a large cam, aftermarket heads, etc then plan a '89-'93 Mustang Mass Air EEC air meter and conversion harness..If you plan on Mass Air a Mustang main harness can be used but it will require some modifications..
