Pink wire is 12v
Black wire is ground
Yellow wire is your signal. Regular volts will read around 5v, but you want the Hz from this wire while running. About 30-40Hz. Look for spikes or erratic signal idle and then slowly open the throttle. Look for the same thing while slowly opening the throttle.
I've gotten a lot of useful troubleshooting tips from easyautodiagnostics.com
