I am hooking up a MSD digital window switch and i need to figure out which is the tach output on the pcm. Ok so it says pin #35 so pin #35 is in the top part of the pcm which is the white wire is this the correct one ? Or is it pin #34 white wire in the bottom part of the PCM ? ? if someone could let me know i would appricate it alot thanks ! !
