    Hoping someone can help me find a solution.
    I would like to have my tail lights be on when my DTRL are on. I know you can switch the the parking lights on and that will illuminate the DTRL and the tail lights. But that also dimms the lights on the dash.

    Any help is appreciated. Thanks

    You can change the brightness on the dash so that when you turn on the parking lights nothing on the dash changes

    Yes, but then at night it is way too bright and it is a mission to have to adjust the dash and the head unit every time.

    The green wire on connector H16 & H17 are the wires to the DTRL. The pink and blue are left & right tail led's. If you splice them together then the DTRL relay will power both circuits (DTRL and TAIL) but you need to up the fuse. And you need to remove the TAIL fuse in the cab fuse box.

    Nevermind, it won't work due to the TAIL circuit always telling the system when it's ON. You would need to cut the wire that inputs this signal to dash...
    It could, but as soon as the stalk is turned to TAIL the system (CAN BUS) will dim the dash...

    Confirm your headlights have this plug:
