MSD window switch
the way my system is wired now is just with a WOT switch..i connected the white MSD wire to the tach,red wire to 12+ AND BLACK TO GROUND. were does the yellow and gray wire connect? this looks a little clearer then my first post..thanks for any help
Wot switch gives 12v to the window switch and low amp side of the relay
Window switch gives ground via yellow wire to the relay
Relay gives 12v solenoids
Thats how I did mine.
