Jeep Wrangler JL

Looking to tow a new JL Wrangler and use my RVI brake which needs a 12V power source. Does the new JL have a power port that is active with the ignition off. Thanks
  • Don't forget to connect the charge wire from the motorhome to your Jeep. This will prevent the brake controller from eventually draining the Jeep's battery.

    I have a Roadmaster setup. I ran a wire from Pin 2 (center pin) through a 15A fuse, and connected it to the Jeep's battery.



    While I currently have a TJ era Jeep, I will be adding a JL version soon (Unlimited Wrangler Rubicon with Eco-diesel).
  • I tried this port in the dash but it does not appear hot when the ignition is off. On my TJ, the port was always active. If anyone is towing a JL , where do you plug your braking device in.
  • No, it is not powered all the time. You can get this Cooltech powerport kit. to keep the power on all the time. It is simple to install.

    I still have to finish running the brake-away line to the interior. Then I can start towing the JL.

  • Can't speak on the JL but our 2017 JKU has a power port inside the center console between the front seats, on the front wall of the console - that port is not switched.
  • Thanks , that is the info I needed.
    Just ordered the cool tech power port.
  • both of the 12 volt port in the 19 JL will drain the battery when they are not wired to the motorhome.
  • this adapter harness is supposed to convert the existing accessory port from ignition-on to always on.

    here is the thread from a Wrangler JL forum where I found it.

    sounds like it does the trick.

    I don't want to hi-jack this thread, but we just bought a new JLUR and want to downsize our rig to a Sprinter C. We'd love to hear from anyone with a Sprinter towing a JLU how it is going. I assume you must be near GCVW.
    Thanks
