i just bought an AEM 3.5 bar map sensor ... on installation do i just unplug the old sensor and tap into the old sensor wiring or am i gonna have to rewire all the way to the ECU, oh yeah im also running a AEM EMS? and where would i run the AEM map sensor too? the intake manifold's vacum line? i really need help

thanks
jimm

 

I believe the AEM sensor has to be threaded into the intake manifold itself. The GM sensor is designed to be T'd into a vacuum line.

Splice your new wires into the stock wiring near the stock MAP connector and disconnect the stock MAP sensor.
