That said color of wire will likely have same function in either harness but connectors will no doubt be pinned differently... Doesn't the MN12 5.0 use a electric fan??? If so there will be extra wiring for it and any other feature not on the Stang... Quote Selected

i just compared ecu pin colors mustang vs cougar Reply #6 – January 05, 2014, 08:27:16 PM Quote from: TurboCoupe50;426817Defiantly not before the 4.6 in '94, I believe those were still OBD-I and maybe states '95(my Calif '95 was OBD-II), all vehicles switched for the '96 model year...it looks like they are completely different. Here is my plan. To swap in a 93 cougar HO 5.0 mated to a T5 :evilgrin:into a 89 bmw 325i. smog legal with a ref sticker in the end.I have the schematics to cut and splice a mustang harness and not a cougar harness into a bmw. I guess I will just look up each cougar pin and cut and splice accordingly. Does anyone here possibly have a link to a wiring diagram for a 93 cougar HO? Quote Selected

Turned out to have a sour MAF, only one I've ever seen that was truly bad... I stuck one on it from a 5.0 stang and it ran much better but I wound up having to get the correct one... Quote Selected

Wiring ?? Are there Any differences in 1993 HO 5.0 xr7 vs 5.0 HO mustang Reply #11 – January 06, 2014, 09:55:05 PM I do know the 91-93 Thunderbird/Cougar computer is harder to tune and doesn't respond as well to mods as the Mustang MAF A9L/A9P computer. If possible I would go with a Mustang wiring harness and an A9L/A9P computer. An 86-88 Thunderbird/Cougar or 86-89 Lincoln Mark VII harness would also work with the A9L/A9P with the MAF wiring added.

Wiring ?? Are there Any differences in 1993 HO 5.0 xr7 vs 5.0 HO mustang Reply #12 – January 07, 2014, 02:38:03 AM OP, have you looked into a Painless harness for your project? Might be easier than trying to convert something to fit your needs...Just get the EEC depending on whether you're going with mass air or speed density, and some required sensors if they're not available on the engine donor...

Wiring ?? Are there Any differences in 1993 HO 5.0 xr7 vs 5.0 HO mustang Reply #13 – January 07, 2014, 02:55:33 AM I'm trying to keep everything stock for now so I can get it to pass smog legally in California. I may just track down a fox body harness ecu & intake and make it a mustang engine. That way I can smog it as a mustang and tune it easier down the road. Quote Selected
Wiring ?? Are there Any differences in 1993 HO 5.0 xr7 vs 5.0 HO mustang Reply #14 – January 11, 2014, 12:46:26 PM Get an aftermarket engine harness for a 91-93 Fox Mustang. An A9l or A9P EEC will bolt right up and work with the T-5. The Painless harness is one pieces which means there is not a separate injector harness or separate O2 harness which makes life a little easier.Finding an original Fox Mustang engine harness with the correct year injector harness and correct year O2 harness that is not hacked or crumbling only to cause you issues later down the road is just a headache waiting to happen. Painless makes one as well as Ford Racing.http://www.painlesswiring.com/webcatalog/largeview.php?SearchField=60510http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=9631Darren Quote Selected
