Hey everyone my friend is in need of some much needed Honda knowledge. He has a 90 Si with a Ls. He is buiding it for a drag car but cant figure out the wiring, I know eveyone will say to use the Si harness, and that there is no wiring involved but however this is not the case. He put the motor in and he went to Honda and bought a FACTORY 90 Si harness, and only about 80% of the connectors work. Everything but the IAC, Map and the Main plug on the driver side of the car, the one next to the injector resistor box plugs right in. He really wants to get the car running so if anyone knows how to tackle this situation, let him know, he would appreciate it.

cuz its the cabin plug that doesnt match up. why would a teg one match up. i think they sold hime an 88 harness as they are WAY different.

i was thinking teg for the b series... i dunno but as far as the cabin plug goes i dunno. i'd just convert the existing harness but if it doesn't have one then yeah there's a problem.

they gave you the wrong harness then. there should be no problems with the wiring here. plug and play. everything should work fine.
