I am installing a RVibrake2 on my 2015 Cadillac SRX. The installation requires a 12-volt cable be routed through the firewall to the battery since the 12-volt receptacles in the cabin are dead during towing. It also requires that the breakaway cable be routed through the firewall.

Question: Where did you route your wires through the firewall? Did you use an existing rubber grommet?

Or, did you drill a hole somewhere in the floor or door threshold?

I am having difficulty finding a location to run the wires and would appreciate your suggestions.

Thanks

I normally follow the factory wiring and use the factory boots when running any kind of wiring or brake cables for towing.

on our 2015 buick enclave I made a a hole in the rubber boot seal that is around the steering column and ran wires thru it.

I am adding the towing stuff to the SRX that I just bought. Although the 2 front 12v outlets are dead without the engine running the one in the luggage area is live all the time. You could run an extension from there. I have an Even Brake and need to connect to the cold side of the brake switch. Have you found an easy place to do that?

As far as coming though the firewall other owners have just drilled a 1/2" hole behind the brake pedal.

After two afternoons of hard work I finally have my 2015 Cadillac SRX set up for towing with the RVibrake 2. After too much time spent attempting to find a way to run the 12-Volt and breakaway wires through the firewall, I gave up. I ultimately decided to drill a hole in the door threshold to run the wires. It was difficult to get the plastic cover removed from the threshold but after that it was fairly easy. I drilled a 1/2 inch hole in the side of the threshold. I installed a rubber grommet and ran the wires under the body to the engine compartment. I used 3M silicone to seal around the wires going through the grommet.
