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.

The MAF sensor gets +12v so you don't want to use that power source at least.

Hmmm i was thinking it would wire up to my MAF plug okay so red to TPS Black to ECU harness ground and green to pin 66?

30-1610/1611/1612
MAP signal - Pin 66
Sensor ground - Pin 50 (tap to this pin)
5V Reference - Pin 49 (tap to this pin)

No, you do NOT use the MAF sensor wires for the MAP sensor. Sounds like you need to read the AEM EFI 101 manual and the 30-1610 installation manual, it is all in there.

As coach stated do not use the maf wires. Just run the wires for the map and iat sensors through the fire wall where the main harness passed through. the map should have a three wire harness that has green,red and black wires. You can find installation instructions on the aem site by typing in the p/n of the sensor you are using. As for tuning it cannot be done properly in 1 day. My tuner has been working on my car for three days. Today he was working on the cold start up part of the map. This is also with me having a base tune off of ben fenners car.

Oh my tuner is pretty good about getting things done fast and since this is strictly a drag car those things wont be to much of an issue thanks for all your help.
