Dodge Repair/2015 Ram2500 external lighting


I am wiring 2 led work lights on a headache rack into my 2015 Ram 2500 Lonestar Cummins. Each light has a red and black wire. How do I do this?  Thanks.

Hi Jess,
The main concern is the polarity of the lights. Usually the black is ground (- post of battery= any metal part of the chassis) and the red would be +12 volts supply. But verify that with the instruction of the lights. I will shortly get a 2009 ram shop manual but I can't reference to your 2015 other than to assume it is identical. I don't know what a "headache rack" is.
