2016 Canyon Supplemental Braking System Wiring

Need some advice from anyone who is towing a new Canyon or Colorado with supplemental braking and the battery disconnected. I just had my Canyon set up by an RV dealer so that I could use my Even Brake 9400 with my battery disconnected using a battery disconnect switch on the negative side of the vehicle battery. I had to leave town, so I can't get it back to the dealer for a few weeks. The installer ran a charge line to the vehicle battery and installed an additional brake switch as required by Roadmaster. He also installed a separate 12V socket kit to power the Even Brake. The problem is that when the battery is disconnected the separate 12V socket is not powered. With the battery connected, the separate socket is powered.

Can anyone who is towing a newer Canyon advise how they are set up if you are using a 12V powered supplemental brake system?

Worst case if you are in a hurry you can install one of these 15 amp 12v sockets at the battery.


and then use a 15amp cable to get to your Evenbrake unit.

Amazon.com: NOCO GC019 12' 12V Plug Extension Cable: Automotive

I also had a 12v receptacle on my 09 Wrangler that wasn't powered when the battery was disconnected so I set this up. As it turned out my Wrangler is one that was manufactured without the steering lock so I didn't need to disconnect the battery. I'll leave it installed for situations where I need a 15amp 12v receptacle like powering the telescope.

Good luck and safe travels!

I did my 12V socket directly off the battery (both + and - posts) so that it's powered even when my battery disconnect is turned to "Off". Not sure why your dealer did it the way they did, as it defeats the whole purpose of using the battery disconnect.

Lots of good info in this thread - Colorado/Canyon

Thanks for the replies. I agree the dealer screwed it up when they installed it. I will have to take it back next month and have them fix it. I will also have them install a grommet where they ran the wires through the firewall. The technician just drilled a hole and left the wires there to chaff through.
