Hi all,
I do not see this specific question answered on the forum so I am hoping someone can help. It looks like @Gregj really understands the DRL setup.
I’ve installed after-market fender DRLs on my 2021 Sport S. These ones are specifically designed to fit the Sport fender and are plug and play. They are similar configuration to the stock LED fender lights in the Sahara or Rubicon. The turn signals include resistors so there is no programming needed. Install went well.

I changed the pins on the wire harness so that the top white light connects to the DRL circuit in the existing body harnesses instead of the parking light circuit. I used JSCAN app to activate the DRL circuit. I live in Canada so DRLs are compulsory. In Jscan, I set the following:
I am not sure if I am missing a setting that keeps the DRLs on even with the headlights on, or if the stock fender lights are wired so that the white lights are powered by both the DRL circuit and park lamp circuit and this was missed in the after-market configuration of these lights. Does anyone know if there is a setting in Jscan to keep the DRLs on while the headlights are also on? Or is this a wiring thing. I could wire the DRL Circuit and park lap circuit together, but I’m not sure if that would cause other problems. I've enabled and disabled the DRL Dropout on Jscan but that only changed their behaviour while using the turn signals.
From a legal standpoint, they are fine the way they are; the Jeep always has forward facing white lights which is what’s required in Canada. I do like and wish the white fender lights stayed on while the headlights were on though like the stock LED setup. It looks much better.
The below picture shows the Pins in the body connector. All are in use except for Pin 4. Park Lamps are only when the lights are on, so them alone do not work for DRL functions in Canada because if they are off during the day. Does anyone who understands vehicle electrical know if connecting the wires coming from Pins 4 and 5 and running those to the white light would cause issues with the BCM? This would keep them on almost all the time.

- Set “Left Dedicated DRL Lamps Output Present” to Active
- Set “Right Dedicated DRL Lamps Output Present” to Active
- Set “LED Dedicated DRL Present” to Active
- Set “DRL Lamp Location” to Dedicated
