Hey @danny01 any update on this? Would be awesome to just update using a Tazer.
All JL models come pre-wired for the fender daytime running lamps. You can take off your front fender flares and see that the wiring harness coming from the engine compartment has 6 wires on it. You will see a white/yellow wire on the driver-side flare harness and a white/dark blue wire on the passenger-side flare harness. These two wires are responsible for supplying power to the DRLs. Both wires originate at the body control module.
However, only Sahara, Rubicon, and Moab models come equipped with the LMX sales code required to activate the DRL circuit from the body control module that sends power to the lights. As of now, the Flascal and the Tazer can't completely activate DRL functionality on Sport and Sport S models. In order for the DRL circuit to activate, 3 checks need to be met:
1. DRL region is set to anything other than OFF. (Configurable with the Tazer/Flashcal)
2. DRL location needs to be set to "Dedicated". (Configurable with the Tazer/Flashcal)
3. DRL toggle from the UConnect screen needs to be set to ON. (NOT configurable with the Tazer/Flashcal)
It's the last check that isn't met on Sport models and hence why the fender DRLs never will illuminate. Sport models don't have access to the UConnect DRL toggle from the factory. In an upcoming Tazer update, Joe will make it so that Sport users can activate the UConnect DRL toggle and then finally be able to turn on the factory DRL circuit.
