i have a 1997 dx civic with the original harness. i recently had an ls engine in it but now have a gsr. the gsr is obd1 and my harness is obd2a, i will be using a jumper harness to run an obd1 p72. i have been searching trying to find a thread showing how to wire up vtec, knock, pressure switch etc.. i also need to know if the wiring is different since im using a jumper harness. if i could just get a website or a forum that shows me or tells me where the wires go or has any information i can use it would help a lot.
