OK i just bought a engine harness but it doesnt have a map sensor harness on it. so now i have to wire up a map sensor directly o the ECU. now there are 3 wires on the MAP sensor. I need to know which one to run to the ECU which one do i hook up to a 12 volt and which one do i ground? the wires are

Green w/ black
Red w/ black
Yellow/ Green

Hmm I just looked at my 1994 Integra service manual and the wires are as follows:

YEL/WHT [(+) for B18C1] or YEL/RED [(+) for B18B1]
GRN/WHT (-)
WHT/YEL (+)

I'm not sure which one's for ground. I hope his helps though.

For some reason your colors are different, what wiring harness are you using?
