hello i was wondering if there was any difference with using the aem stand alone for a 90-95 on an 03..what would i have to change is order to make it work. Is it just the wiring harness that's gotta be changed or is it the whole ecu itself

 

U can get an adapter harness made by boomslang, but you need to specify the pin-for-pin connections. Then you need an alternator controller, and figure out how to make the AEM do VVT.

 

oh ok got cha...
