ok...i know ive been on this subject for a while now but i tihnk i found a solution to clear up my wiring problem...i found this guy that has a 2000 GSR OBD2 Wiring Harness...So my car has a 99 GSR motor in it and i am using a p72 ECU....If i buy the 2000 GSR OBD2 harness and buy a jumper harness(OBD2 to OBD1 conversion) and connect the jumper harness to my OBD1 p72 will everything work right?
