    Want to install 3rd brake light flasher module as I have done in my Rubicon. I need to know color of power feed wire for the 3rd brake light and where to locate the harness. Thanks in advance 34ford

    When I was searching for my cargo light circuit, I found the wiring harness that goes into the 3rd brake light/ cargo light. There were 3 wires.


    -White with black tracer (-)

    -Pink with red tracer (cargo light +)

    -Pink without a tracer (I’m assuming this is brake light + but I did not test it)

    These wires pass through under the door sill at the drivers side rear door, before they make there way up towards the headliner. Hopefully this helps.

    They do make a 3rd brake light bulb that does flash.
