3 wire, 2 bar MAP wiring
I am using a 2 bar MAP for my alky injection. I know the green wire is the output voltage 0-5v. The other two wires are power and ground correct? Do I just hook up to a 12v positive and a ground? Simple answer, thanks!

You need 5VDC to power the sensor. You can reference it from the stock PCM or buy a power supply fromAlkycontrol

just piggyback into the stock sensor center is used for reference signal that's it. you cant use the factory sensor because it will not see pressure when it hits 0 vacumm the sensor is maxed as the 2 bar sees up to approx 15lbs before it is maxed.
