  1. ‘23 20th Anniversary 392 Grill?

    I am also interested in ordering the new anniversary grille. Can you send me info when available?
  2. Has anyone installed the Mopar Trailer Brake Controller?

    This is 100% incorrect. Black is 12v+, white is 12v-, red is 12v+ trigger from brake switch, blue is 12v+ brakes (from controller)
  3. JL - Trailer Brake Controller

    The black at the controller plug is different than the black at the 7 way connection on the rear of the vehicle. The controller needs constant 12v+ then uses that to send modulated power to the brakes via the blue wire.
  4. Working Brake Controller cable found

    Don't use the 3014 harness. Use a 3024 and swap the blue and black wires. No error codes on the dash!
  5. JL - Trailer Brake Controller

    I forgot to add... If you are using the trailer wire kit, you will NOT need this harness. The brake control will be installed with the bare wire harness it comes with. Black to Constant Batt+ (circuit breaker protected at 20 or 30a depending on controller), White to Ground, Blue to your blue...
  6. JL - Trailer Brake Controller

    This harness is ONLY for the JLs with the factory tow package. There is a plug in the area above the location of a conventional parking brake pedal. Swap the black and blue wires at the vehicle side connector on the 3024 harness. The controller side of the 3024 harness can then be plugged...
  7. Trailers at 3500 lbs or under with brake controllers

    it has the wrong connector (male vs female) will not fit our jeeps. Get a 3024 and flip the black and blue wires. - DONE!
  8. JL - Trailer Brake Controller

    I feel like there is a misunderstanding. The 3014 harness is indeed wired correctly for our JL's. The problem with the 3014 is the exemption of a diode on the brake signal wire. The 3024 harness has the diode, but is wired incorrectly. The black and blue wire positions need to be flipped...
  9. JL - Trailer Brake Controller

    Yes. 3024 is the base part number. 3024P is retail packaged, 3024S is bulk packaging if I remember correctly.
  10. Trailers at 3500 lbs or under with brake controllers

    The issue has been occurring when using the manual lever on the controller. We do not install many P3 controllers - it is feature rich and may have an option in the menus to disable lamp illumination with manual brake activation. Most brake controllers will send voltage out the brake sense...
  11. JL - Trailer Brake Controller

    I will see what I can find. If I cant figure it out, worse case, you could install a 3rd brake light converter for a truck topper off of the left and right turn signal wires at the trailer plug, then run the "brake light" wire up to the brake control signal wire...
  12. JL - Trailer Brake Controller

    what harness are you referring to? the 3014? it is possible that Chrysler added some protection into the circuitry to protect the computer when being back fed from the controller. In 2013-2014 the RAM half tons would cook the computer and it would have to be replaced. I feel that if you have...
  13. JL - Trailer Brake Controller

    I haven't had a JL in our shop yet besides mine with a tow package. I will do a bit of homework and see if I can find enough info to confirm an install method. The ONLY hurdle that I anticipate is getting that brake signal... The rest of the install could be done on anything from a...
  14. Anyone install the Redarc trailer brake in the JL yet?

    Don't know if you got to your install yet, if you have the factory tow package - most are recommending a tekonsha 3014 harness. It is not listed to work with the new JL and can cause issues or damage to your jeeps computer. I just did a nice write-up on the correct harness and a modification...
  15. Trailers at 3500 lbs or under with brake controllers

    that 3014 harness can cause all kinds of error codes and dash lights... it is missing a diode to protect the computer. I just posted a write-up on how to make it work the way it was intended. Sorry for hijacking - Just trying to save some Jeeps...
  16. DIY Trailer Brake Controller Install

    This setup will work until you use the manual override lever on the bottom of the controller to activate the trailer brakes. I just posted a thorough write-up on the problem with the 3014 harness that you used and what you can do to prevent all of the dash lights and fault codes that others on...

We install a TON of brake controls, and I have a strong electrical background and...
