    Does anyone on here own a 2021 Toyota Tacoma TRD sport who can post a picture of their OEM LED headlight wiring harness? I am trying to get pigtails that connect to the engine main wiring harness and am having a hard time finding the correct wiring. Thank you!

    Are you trying to instal OEM LED headlights and need a conversion harness?

    What do you actually have on the truck? All the way back to the fuse box is a pretty good run. Are there wires where your headlights were, they are just cut?

    Didn’t you post about this before? I left a post for you to get a hold of me and I’d get you what you need :thumbsup: Are you comfortable using a butt connector to attach a connector to those wires?

    Oh wait, you are trying to install LEDs now as opposed to the halogens? Still doable, and I’ll still hook you up.

    I can make up some connectors with a foot or so of wire coming off them. That work? They will be color matched with the stock wiring, but you’ll have to check a couple wires to verify function. On the passengers side, there are two blue wires. One is low beam, one is parking. There are also two yellow wires on that side. One is high beam, one is parking again. So you’ll need to make sure you have the right blue and yellow wires

    mx150 mating connectors would be a sealed solution.

    Looks like the passenger side only has one yellow wire.

    This is all of the connectors with the LED conversion harness. Looks like the drivers side.

    Didn’t you still have the sidemarker plug intact? One yellow goes to it. Do you have a test light or a meter?

    Definitely the best way to go if you’re comfortable crimping them :thumbsup:

    Sounds like you’re good to make the repair. I’ll shoot you a PM in a bit.
