The motor is a NON-high output, stock 1976 Bronco motor, so it has the 302 firing order..we just put the injection on it from a Speed Density NON-HO Lincoln Towncar (it was free)...I have converted a few Mustangs to mass air.....this harness is way different than a Mustang harness....not even sure if we could swap in a A9L (dif firing order) or other mass air computer.....it does have the port on the back of the computer I do believe. I would just like to send the computer off to someone and have them flash it, putting the rev limiter up to like 6500, just to get it out of the way and leave everything else alone......is there such a place? (not around here in Arkansaw)
