    I found the trick to finding one of these in stock

    After the one on my truck shorted out a couple of years ago, I was having no luck in finding one. Every route I took came back empty handed. If you need one of these get on EZ Wheelers notification list and you'll have one very quickly. In my case it only took 10 days.

    Harness fits but no 12v

    The instructions were easy to follow and the 3rd brake light now works however the dome light for the cap has no power. Maybe a fuse is needed for my 2023 Ram 2500... but where would it be?

    LEER 7-way harness did the job, but...

    The harness adapter works, but was not long enough to reach the power distribution box inside the Leer 180 cap. I had to also use the included wiring in the plastic bag attached to the cap. Took considerable amount of time combining the 2 harnesses using heat shrink butt connectors and the correct size split loom, and routing the harness up behind the left side tail lamp assy. Its done now and working is what counts. In this case def not plug n play.
