Help LS3 Map sensor pinout

[Bow Tie 67]

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

Mods: maybe I should have put this in the help section?

Found it sorry for freaking out.

LS3:
Pin 1 - 5 volts - gray
Pin 2 - Ground (low reference) - orange/black
Pin 3 - Signal to PCM - light green

Matt, glad you found it. Are you trying to go to the power tour with the new motor? I got an L92 also and will be taking notes of all of this for when I put mine in this fall. Good luck!

Yes, those are my plans. I just found out the second venue will have drag racing so I'm hoping to have the spec 3 clutch broke-in to beat on her.
