Troubleshooting A Curt Towed Vehicle Wiring Harness On A 2023 Jeep Gladiator

Question:

I connected the wiring harness to my 2023 jeep gladiator. The turn signals and the brake lights function correctly. But the tail lights dont work. Can you help with my problem?

Hi Philip,

If just the running lights aren't working then you'll want to start by testing the 4-pole connector on the motorhome to see if the signal is sending out to Gladiator. If not then you could have a short in the wiring somewhere, a blown fuse, or your running lights just aren't turned on in the motorhome.

I'd start by making sure that your running lights are turned on in the motorhome. If you're not driving in the dark they probably aren't coming on automatically. You can test the post on the 4-pole connector and the fuses with a tester # PTW2993.

Once we rule out the motorhome as the issue you can then start looking at the connectors on the # C96JR to see if you maybe have a bent or damaged pin or even just a loose connection.

If you've done all this and still can't get the lights on then the wire harness is likely faulty and just needs to be replaced.
