Map sensor wiring I switched to a gm 12223861 3 bar map sensor. I was using a efi source 3bar that fit in the intake this one dosent fit the intake it's a big box with a nipple on it anyways the new one I had to get a different pig tail for and the wires ain't the same color as the harness I have the new pig tail has a black wire a yellow wire and a red with white strip wire I'm guessing the red with white strip is the 5v wore yellow is the signal and black is the ground can anyone tell me for sure so I don't burn anything up thanks
