Introducing the 75Built Auxiliary Wiring Tray. Add electric expansion to your vehicle so you can add all the accessories your heart desires. Designed for simple drop-in of devices, all holes are pre-drilled for multiple options, ready to go. You can also easily customize and expand to your needs.


Compatible Tacoma (3rd Gen) models include Base, SR5, TRD Sport.

Note: Off Road, TRD Pro and models with crawl control have the larger master control and reservoir that get in the way of this panel. It may still fit with substantial cutting/customization, but we do not recommend. Please confirm that your Tacoma matches the engine layout with smaller reservoir as seen in our photos.


We carry a list of Blue Sea Systems devices for you to add some of which are:

Circuit Breaker (7044/7144)

Fuse Block (5025/5026)

Terminal Block (2508/2510)

Bus Bar (2300)

Mix and match as needed. Hardware Kits are available for each device that include various stainless steel screws, washers, nuts, etc. See photos for some of our recommended arrangements. The Tray will accommodate Terminal Bars in 2 sizes as well as Fuse Blocks. Circuit Breakers can be panel mounted or surface mounted. Note: Devices are not included with Auxiliary Wiring Tray.


The Tray itself is CNC machined out of 1/8” corrosion resistant 6061 Aluminum for an exact fit. Layout strategically maneuvers around engine components and rests securely in an optimal location for you to be able to access. Main Tray is conveniently designed to be taken in & out as needed to work on wiring. Simply loosen Arm screws and Bracket screws on Main Tray face in order to release. Our infamous installation guide is included and takes you through the simple easy-to-follow steps. All hardware is included to install the Tray with Arm and Bracket to vehicle. 2-3 week lead time may result during high demand periods.
