You'll absoutly have to swap the harness from the EEC to the engine compartment, and likely have to repin it to get it to connect at the grey and black plugs near the windshild wiper motor.

For wiring diagrams look on ebay(used book dealers sometimes have them as well) for a '87 Tbird/Coug EVTM, it will habe everything you need.

I have a harness from an 87 Sport (Thanks Herb), and i drug it out to my 87 3.8L car, and the connectors by the windsheild wiper motor are plug and play, same color wires, and everything
It's Gumby's fault.

firewall connectors are the same for each year for v6 and v8 ( not sure on 4 poppers)  Like an 86 works for 86 but not for 87 and 88.  but 87 works for 87 but not either of the others.  I'm not sure on the 85's but I'm guessing there differn't as well.
One 88
