Cab-to-Bed Cable Routing

Does anyone have any experience with routing cables from the cab to the bed in the 3rd-Gen hybrids? I need to run 2 coax, and an Ethernet.

I found some information about an overpressure vent by the rear seats, but I can't locate them. Any other solutions? I found the gasket in the front firewall, but was hoping for something in the rear.

 

Most vehicles have a few 'plugs' in the floorboards particularly on the passenger side. I know my '08 and '21 have them, and they can be accessed by removing the plastic trim piece along the floorboard at the door and then rolling the carpet back (between the front of the seat and the dash)...

You can also look under the truck (in the same areas) and just check for the rubber plugs in the floorboard, and that would give you an idea of where they can be accessed from inside of the truck.

 

There is a grommet under the front passenger seat. That is where I ran my dashcam cable to the rear bumper. I just followed the frame rail for the cables all secured with zip ties. 2023 Limited HV

 

A member here helped me out and told me there is a vent behind the subwoofer in the rear seat.

 

The vent is behind the larger panel behind the rear passenger seat. There are a few 10mm bolts that need to be removed then everything just snaps out, peel back the white material and you'll see it centered at the bottom.

 

This is perfect, thank you!

And appreciate everyone's responses
