I'm installing a 93 mercury cougar 5.0 HO automatic with will factory wiring and computer Into an 89 325i BMW. I'm going to leave it as an automatic in the beginning. I will then swap in my t5 after I get it smogged here in ca.
If the cougar was ever made with a 5.0 HO 5 speed in 93. It would pass smog with a 5-speed.
I was hoping to drop it in as a 5 speed from the start but looks like I won't anymore. Thanks for uour help guys
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.
Defiantly 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?
