I have two gauges for my a-pillar and want to know where to wire these to so they will light up when I turn my lights on. I have them now where they could be on all the time but It doesn't make sense to have on during the day. Thanks for any help

i hooked mine up to the illumination in my wiring harness for my dvd player.

^^^^^^^ thats the best place.

the blue harness on the gauge cluster the red and black wire is the one ur looking for

if you have an aftermarket headunit, use the 12V power wire on that.

thanks for the help
