Prodigy Brake Controller Install...Questions and Answers

[davea180]

Now I am desperate with this install. I really am not sure how to supply a brake switch feed to the red wire of the Prodigy. I have seen others post how they installed the controller, but never said HOW they accomplished this. Can anyone help me????

I tried following a post by harryj in 2013 where he said this:

here some info on wiring 2011 ,i have 2013 planing to do instalation tekonsha P3 but quite shur that you can not hook up to the switch directly, i have not yet did any test yet , But from what i see that you found at the switch ,well i think that look like wire that we need is there on info sheet i have post and link , ... BUT i am verry good at this and i think that the right wire to do this might be at the end of the origenal wire harness dodge or any adapter requiered for trailer , at the end ther is 2 or 3 relays one of them must be for braking light you must only hook up at the end of relay not at the end of the 4 wire plug would be pin #85 or 86 and I would use a second relay there to do the switching of 12volt for the brake controle ,just to be safe , here what i have found or go to http://www.commandoc...andura/629.html

I found the Dark Green/White wire in the connector behind the glove box. While the brake pedal is depressed there is 13.38 volts present. Brake pedal in the resting position gives me .20 volts. Is this it? I don't know and I don't know who I can ask. I'm sure the Dodge dealer probably can't help me. Are there any 12 volt electrical geniuses that can tell me if I could use a relay to power the red brake signal wire. Will a relay attempt to energize at a voltage of .20?

I will accept any suggestions here. I am towing a popup at almost 2k lbs. and it is so much easier to stop with trailer brakes.

good luck with your journey...

I have done this just recently. You can use that wire and it works perfectly for my Hopkins agility and I pull a travel trailer that is almost 3500lbs and I can hardly feel it behind me

All-

I have figured it out and have my Prodigy brake controller installed. I used the Dk Green/White wire referenced above in the quote by harryj. I used a relay with a diode to prevent a voltage surge and it works perfectly with my Jayco popup. I just got home from my maiden voyage test drive and aside from some brake adjustments all is good.

I did take some photos, if there is enough interest I can do a brief writeup.

I would like to see photos if you have them. im trying to hook up controller in 2014 journey

Here is the Prodigy install I did in my DJ:

Remove glovebox and locate the BCM up and to the right. The sides pinch inwards and the re-tractor disconnects.

This is the relay I used. Wired as follows: Dk Green/White jumper to #86, 85 to ground. #30 is 12v from a supply. I spliced into the 12v used to supply the controller. #87 goes to the red wire of the controller. It has a diode on 86 to prevent a voltage surge when the brake pedal is released. No voltage is allowed to feed back into the Can bus.

This is the Dark Green/White wire. I stripped it and soldered a jumper for the relay (#86). It plugs into the white body control module seen in the background. It plugs into the upper right with a strange type of locking mechanism. It is self-explanatory when you see it and move the lever.

Here is the relay wired in and mounted to the wire loom. At the bottom of the frame you will see I wired in a SP/ST switch. This is to deactivate the brake signal wire when I am not using the controller. I learned this from another vehicle that the relay gives off a clicking sound when the brakes are applied. I can tolerate it when towing, but not always. I drilled a hole in the back wall of the glove box and mounted it there.

Here is the Prodigy mounted. The area to the left and above the airbag is solid plastic.

Thank you those photos helped a lot. I had hooked up my brake controller for my 2014 DJ with LED lights to the third brake light in the body controller WT/DG wire, but had not considered the relay till I read your article. All of your info and photos helped a lot. keep helping Journey owners.

thanks

Any chance you can show the picture of how and where you spliced in the diode and what size? Also, in the diagram I attached below, to which green wire did you splice into? There appears to be three...
