Anyone that installed the Mopar Tow Wiring Harness attach the Blue wire?
Where does it go?
I thought it would end up being just like the factory option in my other JL, with the brake controller simply plugging in under the driver’s side dash.
Anybody know how the Blue wire does this as it’s too short to reach from the passenger side?

You need to run a new wire from passenger side to wherever you put the brake controller.

I'm trying to figure this out right now. Put the harness kit on as it did not come stock. Now I have a camper with brakes, need to get it connected. Anything new on this?

Connect the third brake light wire to the blue wire to trigger the brake controller. It is the white wire with green stripe. Remove the plastic panel an the right side of the front passenger seat to make the connection then run it to the driver’s side or wherever your brake controller lives.

I have a 2020 JL w/out tow package. I ordered a hitch with harness, but it came with 4 pin connector. I want to tow a small camper with trailer brakes. Anyone know what harness package I should order to be able to tow an RV with brakes?
