Accessory Power in Hybrid Battery Compartment? WEBoost Overland Antenna Install

2023 Tundra Platinum Hybrid 4x4

I am looking to hardwire a WEBoost Cell Booster to my 2023 Tundra. I have searched this forum and the internet and general and cannot seem to find a schematic that details the 12V accessory power system in the new Tundra Hybrid models. I am skilled with electrical work, but I do not know this new system so I am here for advice.

The hardwire cable for WeBoost is 11feet so I am looking for guidance as to how to connect that to the Tundra Accessory power system and route the 11 foot cable to a good install location for the amplifier. I hoped to install the amplifier behind the rear seat, so I am close to the rear of the vehicle where the antenna will be located.

Does anyone know if there is an accessory power connection under the rear seat in the hybrid battery compartment? I see a fuse block that seems to run the hybrid battery fans, but rather than endlessly experiement with the multimeter, I was hoping that someone can point me to accessory power near the rear of the vehicle.

I intend to mount the antenna on either the T-Track provided with my ReTrax bed cover, or to either the Yakima CrossBars or Yakima cargo basket and somehow need to run the antenna cable into the vehicle, ideally as close to the rear seat as possible since that is where the amplifier will be located. Any guidance on that is also helpful.

Mainly looking for that 12V accessory power (OFF When Vehicle is OFF - ON when vechicle is ON or in Accessory power mode). I Do Not wish to directly connect to the 12V starting battery because that is "always on."

If there is a better way to permanently install the WeBoost system I am open to ideas.

Any guidance is appreciated.

 

I always tell people to mount it on a diamond k9000 but nobody ever does. They always use a rhino mount and manually put it up/down.

Maybe I’m the minority here, but I prefer to just push a switch to raise/lower it Makes it easier for garages, car washes, etc etc

 

Welcome to the forum.

I don't think the power outlet diagrams are any different between the hybrid and non-hybrid.
Wiring diagrams are found here:
Ultimate TUNDRA Wiring Diagrams Collection | Toyota Tundra Forum (tundras.com)

They ultimately run off the ACC when the engine is on.





You can find your hybrid fans in the wiring diagrams.
Just search for HYBRID in the wiring diagram.

Good luck..
