I'm going to be towing a car trailer behind the MH. Now I've got to wire up the brake controller and have no idea what I'm getting myself in for. The MH is a 2005 Newmar Dutch Star, and I hooked up the trailer and everything (electrical) works fine. Any help for wiring the brake controller? It's a Tekonsha P3.

The first thing you need to do is find out if you have a brake wire from the trailer electric plug in the back to the front. I just installed a trailer brake controller myself (2003 Coachmen Rendezvous), and while it was a pain, I eventually did find the single blue wire not connected to anything under the dash and used a multimeter and another length of wire to confirm it was the appropriate wire coming from the trailer connector. Once you have that wire, the rest is pretty simple - +12v, ground, and brake light switch wire which are all pretty simple to find under the dash.

The trailer connector brake wire is the hardest part.

Wiring up the controller is very straight foreward.. Just download the owner's manual, (or the install if different) basically it's just a few wires.

Worst case Tekonsha is about 12 miles South of Marhsall, off I-69 between the "old 27" exit and the M-60 exit... I was there just a few weeks ago.. Propane 2.69 on what used to be my dad's farm back when I was growing up.

My 2012 already had a brake controller connector up under the dash. I just had to buy a patch harness to connect it to the brake controller (@ $10). I found the blue wire at the back of the RV taped in the harness about 3 ft back from the 4 pin trailer lights connector. I replaced the 4 pin with an RV type 7 pin that allows for my brake control and a charging wire for the break away system I put on.

The Tekonsha P3 is not at all hard to install - just follow the installation instructions. A call to Newmar should tell you whether you already have a brake controller power feed and/or brake controller output line in the coach. I suspect there may be one and you just have to find it.
