I just picked up my 86 xr7 and I have a tone of spare parts from my 85 SVO so I am looking for any manuals on the Cougar the one I need most is on the pin out of the ECU harness. I have a spare PE controller and want to upgrade the engine for this. Would the non intercooled T-Bird have the same harness as the 86 non intercooled XR7?
Thanks

Pin-out comparison chart for all the 2.3T ECUs.
Short version, ALL non 87-88TC ECUs will plug and play with no additional wiring. The only wiring thing that you *should* do would be to ground the "OCT ADJ" for premium mode. This goes to ground on the PE and to the SIG RTN for the 87-88 ECUs.
Plug it in, wire pin 30 to ground, through a switch or direct, and go. (After you install the big VAM. Your 86 *should* already have the brown-top injectors.)
