I just purchased a 2006 Dynasty from a Family who's Father passed away so I have some unknows.
The Dynasty Owners manual says the coach is pre wired for a brake controller and should have a US Gear D-Celerator brake control but I am unable to find this controller. The PO did flat tow a vehicle with a Blue OX tow system. I am not familiar with flat towing a auto yet.

Would there be a reason for him to remove the D-celerator for flat towing?
I have installed a Teconsha brake control on my 2000 Dynasty but just wondering if he might have removed it for something else. There is just not another controller that I can find and I have been all over this thing for a few days.
Any help appreciated.

There may have been a US Gear operating lever included with the coach when new. I do not know if they actually installed them. Our manual says the same thing. In our case the coach is pre-wired to accept the US Gear brake system and I used it for a while. I found the wiring up under the dash on the drivers side included in a bundle of other unused wires going to a plug that was not attached to anything. Probably the US Gear operating lever would have plugged into that as well as other accessories. I now use the wire as a feedback from the tow car brake to activate a light when the brake is activated. I no longer use the US Gear brake, I have a Demco.

If you did not get an electrical book with your coach, there may be one on here in the files section. It should tell you which plug the wires are located in. It did take some exploring and standing on my head to find it. Enjoy the new to you coach.

Hope this may help. Happy Trails Bert

Thanks Bert, Yea my 2000 dynasty manuals did not seem that accurate either.
I do have a book of wiring diagrams I have just been working on so much I have not even cracked that book.

Thanks for the info. I can't wait to hit the road soon but I just need to get some new fluids and filters in this thing and work on some other details. Sure is a nice coach. It was close to home and was just too good of a fit for us to pass up. It was a short drive home but I sure enjoyed it.

Do you flat tow anything? What tow/brake system do you use?

We have towed a 10 and 15 Malibu LT and are now towing a 2020 Equinox, only because a good deal became available and had the 15 sold if I wanted to. The Malibus were great tow cars for us. We had bought both used, 2 years old. I still have a brand new tow bracket for the 15. We use a Demco Stay and Play brake system. It is installed in the car but easily removable to another car. Not to difficult an installation. The US Gear is no longer available, but there is a place in AZ selling used and new replacement parts from what I understand. I use all Roadmaster tow equipment and I use the Tow Defender, which I modified to go below the tow bar instead of above it for better protection, I hope. I did use the feed wire for the brake controller for a signal wire and a light inside that indicates when the brake is activated. Hope this may help, Happy Trails bert

My Manual says the coach is pre wired for a brake controller and that the wires are. "Behind the I/P Panel." I guess this is instrument panel . I have the two by the floor on the left and the one on top of the dash off.
I have one set of wires on the lower left that has some resistance when I connect a jumper to the trailer 7 way plug. No blue wire however. The blue is trailer brake.
Any help on this? I am just not an electrical guy.....

Rusty Kramer-

Brake Controller Location Guide for Monaco Brand Motor Homes - Unified Tow Brake
Late Model Roadmaster Chassis Installation Supplement for Unified Tow Brake
Service Bulletin for Monaco Pre-Wired Coaches (Unified Tow Brake)

There's no telling how long the Web site will be up, so you should download these documents before the links go dead.

I recommend that you not cut into the Monaco wiring. Instead, use the supplied connector, once you find it. With a picture of the connector I can list the part numbers to match the connector and pins. That way, your installation will be entirely plug-and-play.

Mark, thanks for those diagrams. I have saved them in my files for future sharing and saving. I don't know where you got them but what a great find. This question comes up occasionally.

In the second schematic, it looks like they are using a "Scotch Lok", type connector.
Usually blue.

Getting on my soap box here. I told my electronic techs if I caught them using these they would be fired. In my humble opinion, these are only for emergency/temporary use.
I know they are used every day wiring trailer lights.

Trailer lights are not necessarily life-saving, but a brake sure could be.

Those connections will fail. Not if, but when.

Based on 50 years of working on vehicle electrical systems.

Please use a better solution than those darn things in such a critical application.

In our 2007 Executive it took me several tries to locate the trailer brake controller pre-wire.
It was under the dash to the left of the steering column tied back above the diagnostic connector set.
It has 5 wires: blue, red, & white down one side of the connector; and black-white stripe, yellow-black stripe down the other side. The connector has "66" written on both sides with a sharpie.

Myron, totally agree those connectors are nothing but press on wire cutters. I have had many trailers over the years and the mfgs use those on the brake wires. I have even seen some on marker lights on enclosed trailers at 40K.

Vito, thanks I am digging.

Mark, I will send you some photos of everything I can find I would love to plug in.
On your documents I don't see anything labeled for Dynasty, Exec or Sig ?

Thanks for the info I might have located something behind the lower left interior panel by the seat. Just not sure about the wire colors.
Thanks guys.

I knew the documents didn't list the high-end coaches, but figured they might help you find a connector.

I dug up the following from a 2007 Signature diagram set I have. Perhaps your Dynasty is similar? The diagrams do show an "M-66," as Vito mentioned.

Why don't you tell us how you really feel. LOL
I couldn't agree with you more. 3M should be ashamed of ever producing these things. I'd sooner twist wires together and tape them if I had to do a temporary repair. To me, splicing wires should be done with soldering and heat shrink tubing. A job worth doing is worth doing right.
BTW, when I sold my repair shop I had 61 years under my belt in the auto service industry.
