How to Install a Trailer Brake Controller on a 2008 Dodge Ram


Today on this 2008 Dodge Ram 3500 were gonna install the Tekonsha P3 Brake Controller with direct wiring harness part number 90195-3020P.Our first step is gonna be locating the manufacturers connector for the brake control. The blue connector just above the power control module is the one we need.Well take our direct wire harness and plug directly into the blue connector.Now were plugged into the manufacturers connection, Im gonna go ahead and set my harness aside and we need to mount our brake controller.Well take our mounting bracket that comes with our install kit and simply mount it here underneath the dash. Behind the plastic cover of the dash is a metal bracket and today Im gonna be using self-threading screws to install my bracket. You could drill a small power hole and use the screws that come in the install kit.Now we can go ahead and install the brake controller on our mount.Now with our brake controller mounted, well take the other end of our wiring harness and plug it right into the back of the brake controller.As you can see, the power lit up our brake controller. Now we just need to do some final touch up.Im gonna take a couple of zip ties and secure my wiring up underneath the dash. Simply take the extra from our wiring harness zip tie it off to the manufacturers wiring.

Now I just take a pair of side cutters and cut off the excess from my zip ties.And that completes the install of our Tekonsha P3 Brake Controller with direct wiring harness on our 2008 Dodge Ram 3500. .

I have a 2007 Dodge Ram 1500, That has the exact same set up as on this video listed, my question is that my truck only has the factory four flat hook ups in the back, by hooking up the break control as shown how does my trailer brakes come into play? How would I go about hooking them up? Is there going to be a video showing the process from a 4 flat to 7 flat, video that goes through all details of install not just plugging in the flat connector to 7 prong and tie off excess. How to wire your trailer brakes how to tie in back up lights how to power up trailer through battery cable.ThanksCharlie

We have a video of this whole procedure on a 2009 Dodge Dakota. Not the exact same vehicle, but it will show you the process. I have added a link to that video as well as a tech article that covers the same info.
