Help LS3 Map sensor pinout
 

I bought a GM harness, and long story short, I need to change the Map connector on the harness to fit the Map sensor on the intake I bought.


The Map part # is 12591290 and labeled pins 1,2,3 the harness is labeled A,B,C I need to know the Map sensors High ref, Low ref and signal pinouts.

I'm thinking the easiest way is to check a corvette with an LS3 and give me the wire colors and which pins they go to. I'm hoping the GM harness uses the same color coding which seems to be the case in most instances.

Thanks,
Matt

Found it sorry for freaking out.

Not much sleep lately.
