    Wondering the best way to find the pre wired harness for a warning light. Can I find it through the cab brake light or just have to take the B post apart?

    On my 2011 it was under the map light overhead console. I then fished it through to the third brake light.

    its up in the headliner. they give you a ton of extra wire. You should just be able to pull the A-pillar cover off and pull the headliner down just enough to reach in there with a straightened out coat hanger and pull it over to you. Next, remove the 3rd brake light, run a piece of mechanics wire through to pop out on the drivers side, tape your wire to it and pull it out the 3rd brake light. Splice your wires in (green is power brown is ground I think), and thread it back though so your connections are inside.
