2012 Grand Cherokee wire colors

Hello Jeepers I was trying to install some interior LEDs while changing my headunit on my GC and wanted to hard wire them to the ignition powered 12V under the radio does anyone know the colors of the positive and negative wires? I remember on my WJ they were like green and blue or some odd colors thanks in advance

I have found this site very helpful.


Select your year, then in the "platform" window, scroll to the bottom and select WK.

This could be the page you are looking for:-

It takes a bit of working through, but it's helped me with a lot of wiring on my 2011 JGC.
