    If you have a hybrid and have run switches/harnesses
    Where are you breaching the firewall?
    AND are there any 12v hot points so I don’t have to run my harness all the way to the battery under the rear seat?
    Thanks in advance homies :cheers:

    PS: I tried to search this sorry if it has already posted.

    I searched again with different wording and am now finding several posts. I’ll keep this up and try to answer my own questions or this can be deleted

    There is a hot lug in the passenger side fuse box. You can go through the firewall on driver's side - there is a blank grommet already there.

    I spoke with Mitchell over at Blaze Off-road. Super knowledgeable. He pointed me in the direction of a SDHQ harness, specifically made for the 3rd gen hybrid, that brings 12v power up to the engine bay

    https://blazeoffroad.com/products/2022-2023-tundra-hybrid-sdhq-built-under-hood-power-solution-kit

    set up with a fuse or breaker to isolate the power from your factory electrical system and run a Garmin power switch for all your aftermarket electronic gear

    Seems simple enough and beefy. Price is a bit wild but I’m pretty sure this will be the route I’m going.

    here’s the link for the install

    Punched through the driver's side grommet just behind the left side of the brake pedal. Used the kit that came with the Rave Offroad Hidden ARB Twin Compressor kit. Ran 4 ga from the battery to the bus bar.
