Hey guys, I'm installing the boost gauge, intake temp gauge, and fuel-cut defender this weekend, and I *really* need to know what wire in the ECU harness is the MAP signal wire. Unfortunately, my manual CD isn't here yet.

I have the DIN 3-gauge pod thing, and I'm going to install the two gauges in the first two, and the FCD in the third (fabricated 52mm "blank") to keep it withing reach, and eye-shot.


anyways.. back on topic... I need to know which wire is the MAP signal wire, So I can do the install.


Thanks guys!

as you know there are three wires on the map sensor the black on is earth and blue/brown goes to pin 22 of the ecu and grey goes to pin 43 of the ecu, now one of these 2 wires is the signal wire and the other is a referance voltage supply which is probably going to be a contsant 5 volts so you may be able to test that one with a digital volt meter, good luck ;)
