Behind the glovebox is a jumper on 1998+ models. Older models have this plug on the left strut tower. If you look at the tag on the bottom side of the hood, this plug is mentioned for jumping to set timing. This jumper stops the PCM from it's auto timing adjustments so you can manually read the timing with a timing light, but no need to jump it if you are timing it by ear..........
