I am about to tackle the job of doing my own installation of a Tekonsha Prodigy Brake Controller and I have a few questions to anyone that has tackled it themselves. I have the wiring diagram for the Prodigy and I completely understand the operation and wiring. However, The questions I have are: 1. I have two places to obtain 12V power for the controller at the front of the coach. There is a place in the forward compartment where I can attach to either the Chassis battery or the Coach battery. Which one would be the best choice? I then run a single 10 gauge Blue Electric Brake wire to the rear that would go into the 7 way receptacle. Question 2. I need a 12V positive live wire to feed another spade of the receptacle to keep the trailer batteries charged. I can run a 10 gauge wire from the rear compartment to the correct spade in the receptacle from again either the Chassis battery or the Coach battery. Which one would be the best choice? The rest of the controller hook up is fairly simple, one wire to ground and the last wire to the brake wire. Question 3. Does anyone have experience in finding the correct wire on a 2002 Monaco Windsor PBT to hook into the brake wire? I know where to look for it but with the adjustable pedal unit, it is rather a cumbersome job. Any help would really be appreciated. Thanks so much! Richard.

Well, after waiting to hear if anyone had tackled a similar job, I dove in to this project full bore and decided to use the Chassis battery in both cases. I made that decision based on a more typical installation that would be used for a truck or SUV where they would only have the chassis battery to use. Regarding the brake wire, after crawling on my back and looking at the adjustable pedals for a few minutes there appears to be only two wires to choose from so it shouldn't be too dificult selecting the correct wire. The only difficulty is working in such a confined space to tap into the cold side of the brake switch to get at the wire. I am glad that I only have to do this once. Never again. Next time I'll pay the $400-$500 to have it installed by a technician if I ever decide to purchase a different coach. NOT !!!

Sounds like you have it under control.

I'm getting too old and too fat to do this sort of thing anymore. I did the last one, but paying someone else sounds better all the time!

Here's the instructions from Monaco.

Richard,

Thank you so much for the diagram. I haven't finished the wiring as yet. I have installed the bracket, mounted & wired the 20amp breaker for the controller, and have a 60 foot section of 10 gauge Blue Brake wire coiled up in the engine compartment waiting to be fished through the underneath sections of the coach to the front where I will finish the connections. The ground wire is connected to the ground strip in the front and is coiled with the positive wire coming from the breaker. The only wire on the prodigy controller that is left to be connected is the red one which needs to be hooked to the cold side of the coach brake light switch. This one is the most difficult. Camping World is going to finish routing the Blue Brake wire for me as they have a lift to get under the coach better. Only one hour's labor, that's a deal versus me crawling under to do it.

So with this diagram, it appears that I only have to locate wire #102 at the fuse control center in that compartment to hook the red wire to, correct? The relay system shown in the diagram would be for using the UTB controller only, correct?

I installed the same Prodigy wire harness in my car and it was very simple. The cold side brake wire was easy to get to but the coach is a different situation.

Thanks again for your help.
