Start off by checking the 6-Way connector at the front of your 2018 Jeep JL Wrangler Unlimited. Be sure that none of the wires are touching any wires next to it which would allow power to jump from one circuit to the other.
If that looks good then the next step is to troubleshoot the diodes that come with the Flexo-Coil Wiring Kit # RM-15267. Since the problem is only happening to one side simply remove the diode on the circuit that is messing up and swap it with one on the other side... view full answer...
The Dielectric Goo # 11755 is definitely a good idea because it will help prevent your wiring harness from corroding, but if you don't use it that doesn't mean the Curt Wiring Harness # C56407 on your 2018 Jeep JL Wrangler Unlimited should fail. These harnesses do connect to your Jeep's tail lights so one of two things are the likely issue. First, the connections aren't being fully seated into the tail light harness so you will want to double-check that connection. The other potential issue... view full answer...
When installing a diode kit like the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 on your 2018 Jeep Wrangler JL, you will want to first check the wiring locations to make sure they match as it is easy to get the locations mixed up. Then make sure the diodes are connected correctly so the signal is passing through correctly. You will want to use a circuit tester like # PTW2993 to check the signal at each connection point first.

First I recommend you carefully check the condition of the vehicle and trailer connectors. There could be an internal corrosion issue that is causing adjacent circuits to short. If the trailer has been stored outside for any length of time moisture could have migrated into the plug and caused nearby circuits to short. Also check the condition of the dome light's wiring and bulb socket.
A trailer dome light will typically be powered either by a separate trailer-mounted battery or by the... view full answer...
Sounds like your Blue Ox Patriot # BLU37TR is functioning properly. This unit is designed to sense the amount of deceleration your tow vehicle is apply and put a proportional amount of braking on the toad. Since you are not moving when you tested it with the RV brake pedal it would not apply the vehicle brake pedal. Since you tested the override and breakaway and it worked you are good. view full answer...
I have spoken with my contact at Lippert in the past regarding the same type of issue you're experiencing with your hydraulic leveling system. When this type of problem persists it's almost always the result of a weak power source.
It's important to keep in mind that the leveling system requires a fully charged battery and anything less than a 12.7V output can lead to erratic performance. I recommend making sure your battery is fully charged and in good condition. You can test its power... view full answer...
To determine if the issue is on the vehicle side or the trailer side you can test wiring harness # 118786 on your 2018 Jeep Wrangler Unlimited JL. Use a meter or a circuit tester such as # PTW2993 to test the pin on the 4-Way that is right next to the ground pin. The ground pin is the only one that is exposed on the 4-Way.
If that pin has power when you test it and the Jeep lights are on, then the issue is on the trailer side. If it does not have power, then use the meter or tester to... view full answer...
I recommend you check all the connection points on # C56407 on the Jeep side and the new harness side for any bent pins, corrosion, or debris that could be the cause. Bent pins are sometimes the cause of these types of issues since they're so small and may not be making a good connection. If you find any, just gently straighten them out and reconnect the harness and then test again.
If this doesn't address your issue, certainly let me know and we can continue the troubleshooting process. view full answer...
There are a couple possible reasons as to why the running lights are not working after installing the Tekonsha T-One Vehicle Wiring Harness # 118786 on your 2018 Jeep Wrangler JL Unlimited.
First, since this harness does require that a hot lead be run up to the vehicle's battery, I recommend making sure all the connections under the hood are secure. Since the Jeep's battery is what will actually be powering the harness, you will want to ensure that the black power wire from the T-Connector... view full answer...
Your trailer's stop/turn/tail lights are powered by the lighting signal circuits from your tow vehicle while the dome light would be powered by the 7-way's auxiliary +12V circuit. Since both work, but not at the same time, odds are your issue is related to grounding. All powered circuits on the trailer ultimately share the same ground connection (to the vehicle battery) and it is possible that if the main trailer ground has now corroded it may no longer be able to support all circuits at... view full answer...
Trailer brake controllers like the Redarc Tow-Pro Elite # RED44FR are designed to power the vehicle's brake lights when applying the manual override as a safety measure (to let drivers behind you know that you're coming to a stop). What is happening on your 2018 Jeep JL Wrangler Unlimited is that it's basically detecting that those brake lights are coming on but you aren't stepping on the brake pedal. The computer sees this as some kind of an error with a sensor which is why you are getting... view full answer...
