Hey guys, need some info... I am installing a Digital clock (led) that has 3 wires going to it.. 1 red power wire, 1 black ground wire and the final yellow (second power for the back light). My question is where should I tie in the wires. The red is a constant power wire and the hello wire provides power to the backlight I only want the backlight to be on preferably when the lights go on for nighttime, or just when the car is turned on.. So that means the light for the clock will not light up inti.l the yellow janyone help? Thanks.. Oh.. And with the ground, would it be best to just ground the the chassis or wait! Thanks guys for any help I can get.... Mjclemm

ANYONE ? Thanks...
