Does any one know what RRS might be?
This is on a 99 LS1 PCM.
BLU connector
Pin #6 on my PCM is RED and Circuit # RRS1
Pin #7 on my PCM is GRA and Circuit # RRS2
Pin #53 on my PCM is BLK and Circuit # RRS3
Every single pin has a GM circuit #, but these three.
From what I can figure out
RRS1 is a Sensor signal circuit
RRS2 is the Sensor 5V ref
RRS3 is the Sensor Ground
I have not found the VTD system on system yet if it has one.
I have no PCM to load the Program on and check this out. I have to wait until next week.
