2010 Ram Factory Trailer Brake Controller Install
Picked up the factory trailer brake controller from the Dealer I bought my truck from. Supposedly there was a high 200 unit backorder nationally but it took only a week to get it in.

The controller P/N is: 56029431AF
The beige trim is: 1EB13DK2AA

Installation took 15 minutes after discounting the fact that I was taking pictures.

This is where the factory controller is mounted.

This is the new bezel.

Face of new controller.

Bottom of new controller.

Mount the controller into the bezel. There are 2 screws you'll need to dig up and they're both different sizes. Careful not to attempt to use a screw that's too big or you'll split the plastic casing.

Remove these two Philips screws and don't lose them.

After the screws are out, carefully pull the panel straight back. The ODBC connector and hood release can be left attached.

Once the center panel has been removed, the first of two mounting screws for the cubby are exposed. It a Torx screw.

On the left side of the dash panel is a small access door. It pulls out from the leading edge. Be careful not to just jam a screwdriver in there and pry it open or you'll mark up the sharp edge of the dashpad. I inserted a small screwdriver just enough to get my fingernail in and pull it out. Take it easy here because you can see any marks you make. Plastic trim tools would work well here also.

Now that the access door is open the second retaining screw for the bezel is exposed. Remove both screws now and pull the cubby straight out of the dash.

Up under the left side of the dash (fairly close to where you're working) you should find two grey connectors that are taped to the harness. Untape them and route them to the opening you'll be inserting the new bezel and controller into.

Carefully insert the controller and bezel assembly into the opening and press it firmly into place so the secondary clips on the bezel seat properly into the dash. Plug in the connectors you untied above (they are two different sizes so you won't mix them up) and reinstall the two Torx retaining screws. Turn the ignition on to ensure that all the LEDs illuminate then go off. If it functions correctly then close the left access panel, replace the lower trim and secure it with the original screws.

This is the finished product with protective film removed from controller face.

Very nice!!

If I understand well, it's already to go, just get that extra unit and plug it in? or is there other part to install?

excellent write up !!!! is this only for the 2010 or does it work on the 2009 also ??

Netman66 04-29-2010 08:39 AM

This is only for the 2010 models. As far as I know it won't work the same for the 2009 since the harness plugs aren't all present. I imagine it would mount exactly the same, but without the harness connectors you'd need to figure out what to tap into. There are other forums that show the connector pin-outs and what needs to be done to rig this up in a 2009.

Yes, you only need these two parts for the 2010 models.

This is very helpful. My controller is on back order, I was told it could be 2 weeks. Seeing your write up I am now happy to know I can install this myself.
Thanks for the info and great pics.
