I tied the TPMS repeater into the “drag light” circuit located in the rear curbside engine bay. It is always powered on and is a great place to mount it. I also wired a switch next to it so it can easily be turned on and off eliminating the wire clips.

Just to offer up a different viewpoint, I hooked mine to the house batteries. I figured the house batteries will be powered up whenever I'm driving.

When I bought the coach, the repeater was behind the driver's side nightstand. I keep getting dropped out signals. So, I chose to move the repeater.

I placed it above the main breaker panel in the space above the bedroom drawers. There is a large empty space in there. Basically behind the switches for the bath area and bedroom.

This enabled me to utilize the 12 volt circuit panel that was right there.

I wired this into the closet above the rear fuse panel, passenger side. It has usb sockets and a digital readout and a switch to turn it off and on. Thats where I plug in my extender. Works great. Got it on Amazon.Click image for larger version

I mounted it to the battery bay ceiling, and hooked up to house batteries with the alligator clips for now. Left Monday morning for vacation, pulling my boat. Decided to leave the repeater off since it was working fine without it in the yard. Lasted about an hour before I lost signal to both boat trailer tires, and the left rear inner tire on the coach. Hooked it back up and all was fine for the rest of the drive. I’m still gonna hook it to ignition switched power later.

Mine is not switched. I wired it to one of the fuses on the ceiling of the battery bay. Its been like this for 4 years.

I drive with my parking lights/headlights on, so I just tapped into the license plate light circuit-- made mounting the TPMS repeater very easy.

I considered that. But I figured I’d forget to turn the lights off and kill the batteries since there’s no buzzer to remind me.
