    Looks like you are wiring it into left taillight. That would explain why, only left turn and brake is working. Most get wired into trailer harness.

    just wiring the left turn signal and brake into taillight. only one or the other works… all other signals are fine. the rest are wired into the trailer harness but there’s no running lights in them

    Before you fry the taco's combination meter, don't combine vehicle wires AND towing wires to the added light bar. Towing combines Stop N Turn on one wire for left, same for right.

    i mounted mine just beneath the spare tire access hole. just had to remove the plastic bushing on the hole.

    but +1 on the trailer harness adapter. i always mod sacrifical harnesses like that if i can. makes pulling/modding easier to keep the oem plugs.


    after install 1/8th of the bar burned out. so this spring i need to replace it. not super happy about it given the cost, and their warranty page seems to indicate it's a fairly common failure, going by what the warranty doesn't cover...
