    I made this for my 2022 Access Cab but the fit is the same on the 2nd gen.

    If you want to put a fuse block in the bed of your Tacoma, you can use this fuse block mount to keep it dry and free of dust and dirt behind the driver's side taillight. A mirror image version of this fuse block mount is also available for the passenger side.

    I ran 10AWG to the back of my truck & used a fuse block from there for various lights and accessories.

    [​IMG]

    I started by looking at prefabricated project boxes but none fit my exact dimensions and all would have required extensive cutting for all of the holes I need. In the end is was easier to pre-fab what I wanted in cardboard and then print the fuse box with all of the holes right where I wanted them.

    This fuse block housing was designed for a fuse block I found on Amazon

    WUPP 12 Volt Fuse Block that I got on Amazon
    . It is slightly more compact than the Blue Sea fuse block that I used in the cab. It has a negative bus which is handy for this location. The ground wire can be run back to a factory ground point located on the frame above the driver's side rear tire. Its' only about 3 feet away.

    Here the fuse block housing is installed behind the driver's side taillight. I'm using existing holes for the bolts that hold this in place.

    A hole will need to be drilled for the top machine screw to secure it to the body.

    And starting to run wires from a switch panel in the bed to the new fuse block:

    In addition to the 10AWG wire, I ran multiple wires to power lower amperage switches and relays. Here I'm wrapping that wire harness with multiple layers of sheathing. The copper pipe is just used to make it easier to add sheathing to the wound wire harness by running the wire though the pipe and the sheathing over the outside.

    If you are going to the trouble of running primary power to the bed & will probably want a couple of wires for relays for rear lights, its only a few bucks more to run more wires than you currently need & future proof your work.

    The fuse block housing was designed using FreeCAD software and 3D printed using a Prusa MK3S 3D printer:

    Now with improved space for wires that connect to the fuse terminals.

    I used these water proof relays from Amazon

    Once every thing is installed I add a cover to keep dirt and water out.

    Note: new version has translucent cover so LED lights for blown fuses can be seen without removing the cover.

    Also available printed in mirror image for passenger side.

    I would have no use for this what so ever but its very cool. My only worry would be that if you got rear ended the chance of the hot power wire shorting, I might bother to put a switch in the cab to kill the hot power wire if ever needed.

    Projects like this make me want to buy a 3d printer.

    That is a really good point! I suggest using a fuse in the engine bay for the positive wire to this taillight fuse block. Also, there is a factory ground point on the frame just inside the left rear wheel.

    I have no use for this at all but I keep seeing this thread and am impressed with the fuse box solution each time.

    Not much different from any other hot wire in the truck. Any aux fuse panel should have its own fuse or breaker on the supply anyway so it shouldn’t be an issue. Anyone with a cap has a wire for the light already. I’d would just upgrade that wire to the new panel and tie the cap light to the new panel along with any bed accessories.
    On a corner does seem a bit exposed though. The old 05-11 small bed cubbies might be a better option.

    Yeah, this whole box is on its own fuse in the engine bay.
