MAP sensor Help
 

Hello TCC!
I have bought a GM 3 bar sensor, my EMS has it in the settings. My Problem now is, I have no idea how to install it. My current Throttle Body DOESN'T have a map sensor, and the GM piece obviously won't fit. Should I just sell my 3 Bar and buy a Hondata MAP sensor? Or if a Xenocron DIY map kit what I need?

Mount the MAP to the firewall somewhere, run a vacuum line to the manifold.

...And plug the hole on the Throttle body?
The Vacuum line from the Master Cylinder?

Can I do this instead?

you can buy an adaptor that screws onto the stock MAP location on the throttle body that has a threaded hole and barbed fitting for a vacuum line.

Or if you have a throttle body mounted MAP sensor, even if its junk, just put it on the throttle body and use the manifold as your GM 3 bar's vacuum source (like chris_v2 said).
