    Need your brains for a moment.
    Have an 06 4x4 DCSB with tow package. I am confused as to whether or not I need to buy a harness adapter for my Tekonsha P3 brake controller. I have done searches, etc but am not quite clear on it. How would I install it without buying the harness? I bought a used P3 that also came with a Dodge harness.
    Thanks guys!!!

    Oh yeah, also. Noticed this brake controller harness is cheap, but says it is for 2007-2011. I have an 06. Does the 07 wire up differently? This I have not searched yet, sorry.

    I replied to your PM, but will post up here too.

    No, you do not NEED the vehicle specific harness. I wired mine with the factory pigtail (included when you bought the truck) and it works fine.

    Here is how I did it.

    I am installing at this moment.

    Regarding ground wire. So the brown wire goes to the white wiring from the Prodigy3. I don't need run those wires to a metal piece?

    I have a 2012 with tow package.

    Can someone confirm if this is correct? I'm pretty confused by what the Tekonsha P3 controller diagram says and what the pigtail harness connector says. I have a 2014 DCSB with tow package.

    Not sure if you got your answer yet, but I am starting the same project as you today and am going to use the wiring scheme posted on this thread. I will let you know if it works shortly ;)

    HootYeah - you are good to go with this wiring diagram, just splice the wires according to the diagram in this post and you should have no trouble. I just finished the wiring, plugged in the P3, and it powers up and I can tweak with the settings. Will test with the trailer later this week but anticipate no problems. Now on to mounting the unit, best of luck to you.

    I got impatient and just went for it. First time I've trusted someone online lol... Worked perfect. Jacked up my trailer and tested the brakes to see if they were engaging. Excited to get this beast out on the road! Will be towing a 1986 22' Wilderness trailer by fleetwood.

    Also, there is a cubbie right of the steering column that you can pop out, I ran the wires of the unit through that hole without any of mounting screws, surprisingly the pressure from the wires in the back after the insert/cubbie is popped back in holds the unit perfectly. I'm going to devise a way to make sure it stays stable without drilling holes in my truck. To much of a sissy for that....

    I thought pretty long about where I wanted this and I feel like having my right hand ready to reach down near the steering wheel to hit the manual trigger is ideal. will stabilize it somehow but it's pretty solid.
