hey, just threw a Z6 in my 1990 Std hatch. The wiring was from the old zc, which was a 89. That explained the problem I had with the car, 89 harness was different than 90. My hatch has alreaddy been prepped for MPFI. I got a harness coming from a 90 Crx Si, OBD-0 MPFI to OBD-1 MPFI. Question is..........once I wiring in the injectors and double check the crank sensor wiring, it should work, correct? n00bs dont try and tell me that 88-91 are the same they are not with wiring. I just cant find a cannon plug pinout to verify it for my self.
