The stainless steel unit has that info on a sticker attached to it. The brass MAP sensor is lacking info on it. From memory it should be Red gets +5v (usually tapped into the TPS sensor +5v source) and black gets grounded to the ECU grounds anywhere, and green is the signal wire that goes to the MAP sensor input pin on the ECU.Another thing is i can't find a wiring diagram on the AEM 3.5bar map sensor i am assuming it's simple i just don't know which pin is what.
The MAF sensor gets +12v so you don't want to use that power source at least.
