Question
Question OK so i have a 98 z and just recently did a ls2 swap and swapped out my 98 pcm and harness for a 01 pcm and harness. I found that the 98 harness had an extra white plug under the dash in the car, now that the 01 doesnt, the cars harness inside has nothing plugged into it......and now that my car is running it is showing the oil pressure gauge pegged out before you even turn it over and also when its running. there is no voltage either. Obviously it has voltage, its a brand knew battery.... Is that plug the problem for these 2 gauges not to be working?
