If you expected it to fit, you were misinformed.



Notice the nipple? Run a vacuum line to it.

 

As posted above, you use a vacuum line to the intake manifold for a reference. You also wire the ground, power & signal to your engine harness.

You shouldn't install an aftermarket map sensor unless your engine computer is setup for it.

 

yeah i have a chip from phearable for using the 3bar map so im good on that. so i just leave the factory map sensor on the throttle body unplugged so it blocks off the hole and run a vaccuum line to the new one? does it matter what line i tap into to go to the 3 bar map? should i use a different one from the one that runs to the wstegate and bov?

leave your stock map sensor in and run a vacuum line to the GM Map sensor, mount it on your firewall somewhere...

 

where should i tap into for the vacuum line?

"Bananafold" That was perfect! I like it.
