Map sensor wiring

[deuce93t]

I have a 2 bar map sensor in my car and i was wondering if any one can tell me what wires mean what so that i can change over to the 3 bar map sensor and push more boost! oh by the way i have a 2nd jen motor!

There are 3 wires.
PIM (pressure signal, voltage change with boost),
VC (constant 4.5-5.5 volts)
E2 (ground)




Colors might be different depening on what harness do you have.
On my Celica, PIM = red-white, VC=pink-blue, and E2 = brown
You can use a voltmeter or ohmmeter to test that.
