OBDI lt1 to OBDII ls
so ive searched and searched. i cant seem to find any info on what is needed harness wise when swapping OBDI to OBDII. I have a 94 camaro and want to swap in a lq9. i already have a speartech engine harness to allow the lq9 to plug into the lt1 body harness. what im having trouble finding is what needs to be done about the data link connector under the dash? am i gonna have to swap dash harnesses with one from a later model? any suggestions would be great thanks!
