    You won't use all the wires that comes with it.

    Right, looking at the two pics side by side, you’re clearly missing most of the wiring on the 18-pin connector on the “top” of the Maestro

    Idk what their return policy is but I’d try and just return it to Auto Harness House and/or just order a new harness and cut your losses, I haven’t looked at the pin outs but I’d be happy to if they’re available, but this 99% looks like you’re missing 14/18 of the wires on that connector which would make sense why that shits not working.

    Edit: Trail Grid Pro lists your radio for 2014-2021 Tundra, but Crutchfield says it’s compatible for 2013 as well so I’m guessing TGP just doesn’t get enough pre-2014 requests to stock the trim for em, anyways Crutchfield says you’d need the harness you linked as well as the:


    The Harnesses should be clearly labeled if they’re from iDatalink directly
