MAP sensor:
-- red from AEM sensor goes to grey from MDP sensor on top of manifold = 12v power
-- black from AEM sensor goes to black from MDP sensor = ground
-- white or green from AEM sensor (they now have a white wire but the instructions mention green) goes to yellow from the MDP sensor = signal
AIT sensor:
-- black wire from the maf plug and the red/blue wire from the maf plug are for the ait sensor. polarity does not matter, but if you have a white wire for the pigtail that is power and black is ground. You would hook black from the pigtail to the black wire from the maf sensor and the white wire from the pigtail will go to the red/blue wire from the maf sensor
Boost solenoid:
-- red/yellow wire is the 12v switched ignition power and the light green wire is the switched ground wire. Wire the positive side of the solenoid to the red/yellow wire and the ground side to the light green wire.
