Trailer Brake wiring question
I will be wanting to install a trailer brake controller in our Berkshire 40B after we pick it up.
The service dept. said that all the wires are labeled, yet in the same breathe mentioned that if they couldn't find the correct wire that they simply ran new wiring from the dash back to the trailer brake plug in location.
Does anyone here possibly have any experience in wiring up and finding the correct wires under the dash to accomplish a nice clean no hassle installation?
Thanks in advance,

Sorry I can't help, but it amazes me that something that expensive, they can't put in a factory controller for a few bucks.

Based on your statements I feel like there is more to their explanation. There is much more to trailer wiring than "a" wire.
Are they installing just the brake controller? Or are they doing a full trailer wiring plug?
Is there currently a plug at the back of your rig for trailer wiring and you are just missing the brake controller? If so it should be an easy job. If they are creating the plug from scratch there is a lot more to it than one wire.

This is a Berkshire page. All Berkshires come with trailer wiring plugs, and the appropriate fusing in the rear power control module located next to your inverter charger on most (except side radiator) models. There is a plug under the dash where you can attach a pigtail to connect a brake controller. The dealer should have no problem with this if they know what they are doing.

I'm sorry. When I said just run a new wire to the rear I was keeping the statement in it's most simplistic form.
They are not installing the brake controller for me, I was only picking his mind as to if the wires were pre run on the coach and where they would be located under the dash.
I have installed more controllers than I care to remember, but one thing I have always learned is to not take things for granted when it comes to locating hidden wires. The worst I ever faced was installing a controller on my Kenworth T300 Toter Home.
With the assistance that I have received here I have a pigtail wire coming from Amazon for the Freightliner plug.
Thanks everyone,

Brake controller
I think I would insist that the dealer instal the brake controller, especially if you have not done that before.

No big deal, I received both the controller and Freightliner wire harness for a simple plug and play installation once we get the coach home on Thursday.
