Hey all, Hoping a 7 guru here can help me with a question,
Which wire going to the boost pressure sensor is the ground?
Wires are:
White w red stripe
Black w red stripe
Red w black stripe
Red w blue

thats odd... should be brown with a black stripe. same brown with black stripe wire grounds both the afm and the pressure sensor. for s4 cars anyway... so im guessing yours is an s5? i would say its either the black wire with red stripe or white wire with red stripe. japaneese cars use alot different color codes for thier wires than typical american wires.

Your looking at the wrong sensor or?????????????

The Boost sensor has a brown/white, brown/red, black/white and either a brown/black or pure black wire for the ground. That's for a series four car.

Most likely the black/red. I know what the other wires do in life. The trace of red on the black is new to me. Must be a 88 model car, I figure.
