Any one know where and what color the tack lead is on a 97 psd. Trying to get my remote start-alarm working. Thanks Dave

With a diesel the PCM is in the drivers wheel well, but I believe the white/pink is still the tach.

 

Thanks Cookie88 & ReAX, I tried the white pink, Got 5.60 volts at idle and whent up from there with more throttle. Now I just got to get the alarm box to learn the tach signal
