I have just gotten a 1991 teg ls. The owner b4 me took the motor out. Needless to say the wire harness in the bay is next to distroyed. I am goin to put a ls/vtec motor in it. And down the road boost it I just wanted to know if it was a good idear to go to obd1. Or just stick with the obd0. And where and i get the engine/chassis harness for the convert?
