Can I add 2012 Factory trailer brake controller to 2010 Expy EL

[MattyMMA]

Hi all,

I've tried some searching and I found where people were looking to add the factory trailer brake controller to newer models and even then, not all the information.

What is required to add the factory trailer brake controller. We have a 30' Keystone outback and are planning a 25+ trip next June-July and would like something better than I have. But I'm 6'4" so I would like to minimize taking up any of the real estate in my drivers area.

Other than adding the factory controller, are there other trailer brake controllers with a remote mount that I could possibly add to that area? I've seen some models by Redarc? But they are Austrailian and not sure how it would do and intergrate with the Expy.

2010 Expy EL Limited with rear load leveling.

Thanks for any help.

Matt.

WAYYY old thread, but curious what you ended up doing? I was surprised to find out from the local dealer that there wasn't an OEM option for the 2010 Expy.

Tekonsha P3. Ridiculously easy install. You can put the head unit wherever you want. Where I have mine on my 07 in this pic can be a little in the way getting in and out sometimes.

I used the P3 also but mounted mine to tge right knee bolster. Makes getting out easier than under the column

Eventually I'll probably move mine. I can't remember why I didn't end up with it where you're talking about, but there was a reason at the time. If I get rid of the hinge part of the mount, mine wouldn't be bad. I only keep it there when I'm towing anyway.

My 17 model only has a 4 pin plug in the rear. But when I looked under there it looks as if the other wires are there to? So probably could install a 7 pin and add the brake controler, but idk. Those just plug in under the dash right, and vehicle has to be ready for them? Atleast that's how my Suburban was, but it alrdy had the 7 pin connection in rear.

I think you'll find they're all pre-wired for the brake controller from the dash back to the rear bumper. I can't remember for sure, but I think all you have to do is plug in the right 7 pin connector harness back by the tail lights. I don't think it's slice and dice to install it. I'm sure someone here knows and can comment. All my rigs have had the HD towing package, so I haven't had to mess with it. If you can't find out, let me know. I have factory manuals and factory wiring diagrams.
