95 HO into 88 V6 T-bird September 06, 2017, 08:08:16 PM Hey guys I thought I'd start a new thread with some of the issues that I'm having with my engine swap. I have the engine in the car with all the connections hooked up. I have an engine harness from an 87 5.0 cougar trying to match to the body of an 88 V6. The connections don't match very well, and I need some input on what I need to do from here. If anyone is familiar with which wires to hookup or leave disconnected, please let me know.
