[sidewaymambo]

Hi, All

My project is getting more fun now..I am looking at my Q45 AFM, it has three wire and I know they are 12V, signal and ground (or AFM ground), but which is which?

Can someone out there can suggest me how to find out by multimeter (spell / typo)? or can point me to the site has the wiring diagram?

thanks

WIth only 3 wires - should be able to make an educated gus based on colours.

black - probably earth

red or brown - probably 12v constant

other - signal

if you have a PFC - try it out on the diagnostics screen with ignition on only
