    I’m installing new aftermarket fog lights and need some help. Can someone please confirm if this wire harness is supposed to power fog lights? It’s female with 3 pins. The wires are purple, white, and green. I have an aftermarket ARB bumper with fog lights and the shop that installed the bumper, wired the lights via a different source and NOT the pictured harness. I need to know if I can use the pictured harness to power my new fog lights.

    Does the pictured harness use a pigtail to power the factory fog lights? I sold the factory bumper and unfortunately think I may have sold it with the pigtails still connected (if that is the case)
    I need those pigtails to power my new lights because they can be directly powered/plugged in from the back of the lights with an H11 harness.

    Thanks!

    UPDATE..

    This is the plug that has been powering my current fog lights.

    looks like the shop snipped the old plug off and wired up the plug required to power the arb fogs (HB4)

    note the blue/white wires…

    can someone confirm that this blue/white wires are the factory wiring used to power factory fog lights?

    The first plug is for parking sonar sensors on the front bumper. Your truck doesn’t have those since nothing is connected.

    Yes the driver side fog light wiring has a blue power wire and a black and white ground wire.

    ended up cutting the old hb4 male off and tapping into those wires! The passenger side is pink and white. Thanks man!
