It lights up but I need to know which wire of the cup holder LEDs is the cold and which is the hot. Trying to put it in right now. If i tap into the LED power will it dim it or shut it down all together?

 

what gauge is the wires? Probably not unles they are ultra thin because leds use almost no juice. I use them for accent lighting on my bike and can run them alnight with out even putting a dent in the battery (this is a tiny ___ bike battery) so that tells you how little juice they use.

 

red is hot black is cold. i tapped these when doing my cc install
