I got inspiration for this design from the Ed Martin Youtube Channel, where they installed an SDHQ Air Compressor in a 3rd gen Tundra. https://www.youtube.com/watch?v=5DAYLXZA51c

Ed Martin Toyota used the SDHQ ARB Twin Air Compressor Mount with Remote Air Chuck. https://sdhqoffroad.com/products/22-current-toyota-tundra-sdhq-built-arb-air-compressor-mount

The Toyota OEM parts needed are listed below: -qty 4x 90148-A0006 (M6x1.0 screws) -qty 1x 85530-0C081 (bulkhead connector, originally a 120v AC wall plug)

The other parts you'll need are listed below: -qty 4x #10-24 x 1/2" button head screws. https://www.mcmaster.com/90600A450/ other screws may work but the plate was designed for the diameter of a standard #10 screw. -qty 4x washers for #10 screws. https://www.mcmaster.com/90313A103/ -qty 4x nuts for #10 screws. https://www.mcmaster.com/91841A011/ -qty 4x M6x1.0 nuts for OEM screws. https://www.mcmaster.com/94645A205/ -qty 4x M6 washers for OEM screws. https://www.mcmaster.com/91100A321/ -qty 1x 1/4" drill bit All parts listed can be found at lowes or home depot for much cheaper BUT not nearly the same quantity. Your cost per fastener goes way up at box stores.

Cutting the OEM power plug has some trial and error to fit the plate. It depends which orientation you opt for. I tested vertical orientation but found that the chuck dust cover wouldnt get out of the way enough to easily plug in an air hose. A dremel with a cutting wheel is the easiet way to trim the plastic. 4 holes will also need drilled to mount the plate to the OEM part.
