can a si wiring harness work on any other obd2 ecus or do you have to use a 99-00 si ecu?

 

harness is a harness, OBD's have to match. You gotta have the samesensors and locations, Thats really the only difference. Hey i got your message and tried to call you back, no one answered. You said the coil wasnt sparking ? did you ground it ? if not get a new coil and ignitor just to be safe.
