3 Bar Map Pin out connections I have an AC Delco 12592525 3 bar map in my car. I am trying to connect the pig tail for it to my 01 LS1 harness. I can not seem to get the sensor to read. I have found what pin on the LS1 harness has +5v but cant figure the others out. What I need to know is in red. - SOLVED - Below is the correct info.
LS1 harness:
Pin A: Black wire, Confirmed ground to PCM Blue #54
Pin B: Bright Green wire - Confirmed Signal to PCM on Red pin #34
Pin C: Tan wire, Confirmed +5v PCM Blue #48
12592525 3 bar map -LS3-:
Pin 1: +5v from PCM from Blue #48
Pin 2: Ground from PCM Blue #54
Pin 3: Signal to PCM from Red #34
These PCM pin numbers only apply to the LS1 F-body harness.
The pin out on the LS3 will be the same on all MAP's with this connector.
