Title: Electrical hook-up for towing
Post by: Panbox108 on June 03, 2005, 09:35:25 pm
Yahoo Message Number: 16766 (http://groups.yahoo.com/neo/groups/Country-Coach-Owners/conversations/messages/16766)Made my maiden voyage three weeks ago with our new 04 Intrigue Ovation. Got to say, "This is one fine machine". I wish I had been smart enough a year ago to purchase a Country Coach rather than working up from a gas powered Gulfstream that self destructed on it's first trip from South Carolina to Buffalo. I returned that one and purchased an "Alfa, SeeYa" urghh! from bad to worse. Finally did some homework and went for the Country Coach. All within a year. This unit is 5 or 6 feet longer than the Alfa and gets about 25% better fuel mileage. The handling is absolutly great, not to mention the soft ride and phenominal power. Ok .... So all you people already own CC and don't need to listen to me wasting time ... sorry.
I do have a question though. When I initially got ready to leave, I connected my 04 Tahoe to the CC and discovered I had no brake lights. Drove to the CC dealership and was informed I had blown a fuse (Simple enough)! When the fuse was replaced, it instantly blew when I applied the brakes. We finally discovered that CC wires their system differently than most of the other manufacturers. I was running 4 flat and the CC brake light needed a different connection. I was then told that my Tahoe could not be configured to the CC standard, so they removed the CC control board and replaced everything with a standard 4 flat hook-up and a brake relay. Works fine, although it just doesn't seem like the right solution. Anyone have any idea how to do this hook-up correctly? I would like to reinstall the original CC equipment and make whatever changes are necessary.

Yahoo Message Number: 16771 (http://groups.yahoo.com/neo/groups/Country-Coach-Owners/conversations/messages/16771)I hope I am not misunderstanding your post, but I hope you saved the parts. A very cool feature of our Affinity is that you can jumper configure your rear plug from a five wire to a four wire.
Most trailers are four wire ... left turn, right turn, tail lights, and ground. Brakes are both left and right. Five wire pulls out the brake lights as a separate circuit.
Our Journey was a five wire, and our Dutch Star was a four wire. Sort of a pain if noone told you this. CC just requires you to move a jumper, pretty cool feature. The nice folks on this forum helped me find it, it was not where the book said it was, but after that, even a dumb Swede could do it (I did). Maybe your coach does not have his feature, but I sure would not like it if someone ripped out this board and tossed it.

How did you wire that Honda? I have an Acura MDX that I am going to start towing (replacing my Suburban). I am wanting to determine if there is a clean and simple way to do this.
Thanks,

Yahoo Message Number: 16773 (http://groups.yahoo.com/neo/groups/Country-Coach-Owners/conversations/messages/16773)We have wired both our CR-V and our Pilot the same way. We ran two wires (18ga) from the front plug and into each tail light area (left and right side). One wire from each side is common at the plug for the tail lights. Cut the wires from the two filaments of your choice (you can select tail and brake by watching which light up before proceeding).
A diode is placed in each leg, and in the car side of each wire, four diodes per side.
The diode theory is as follows ... You want the current from the front plug to get to each filament, but not back to the car wiring. And you want the current from the car to get to the filament without getting to plug (and into the motorhome). So, the current can come from the car thru the diode, and get to the filament, and the current can come from the plug, thru its diode, and get to the filament. Neither current can go the other way, car to the plug, or plug to the car.
Let me see if I can hack this out with ASCII characters ...

Save your self a lot of trouble and hook up a separate lighting system for your car. Don't tie the CC system into your car system just add a light bulb and socket to you existing tail light housings, run separate wires to the back and plug it into CCI system. Thats how Lazy Days and many other people do the tail lights, we have done this with 5 vehicles. It's simple and you do not need to worry about you car system.

Thanks for the reply. Yes, I did keep the parts. The PCB they removed was undamaged and will be easy to replace. I had two mechanics working on this thing for almost 8 hours. Neither could agree on how it should be wired so as I said in my post .... They just removed the board and replaced it with a brake relay. When I had the Tahoe wired for towing, rather than install a diode system, I had them install separate bulbs in the rear tail lights. Figured this would eliminate any future problems ....(Was I ever wrong!) I would be interested in trying your wiring configuration if you remember how you did it. I would expect the wiring to be similar between the Affinity and the Intrigue, although I will check with CC. Really appreciate the help ....

Bill ....
Thats exactly what I have, separate bulbs mounted in the tail lights. It causes the brake fuse to blow on the CC when the brake lights are applied. This system worked with two other coaches with no problem. CC has a separate feed from the brake lights ... they are not common to the directional signals and cause a direct short when connected together. Perhaps Lazy Days knows to create the jumper connection John wrote about in a previous post. Thanks for the reply ... this is a frustrating problem.

Yahoo Message Number: 16778 (http://groups.yahoo.com/neo/groups/Country-Coach-Owners/conversations/messages/16778)Don't know if your coach is like our 2002 Allure, but, the tow wiring board is under the bottom drawer in the bedroom cabinet stack (passenger side rear). We had to change the little jumper (per the instructions in the manual) to make the wiring correct for towing our GMC Yukon. Also, we elected, as you did, to forego the diode route and we installed auxilary lamps in the taillight housing. We ran wiring from these lamps all the way to the front of the Yukon for the hookup from the coach. Ours has worked very well for two years.

Yahoo Message Number: 16779 (http://groups.yahoo.com/neo/groups/Country-Coach-Owners/conversations/messages/16779)I agree the separate tail light is pretty easy, but I did not want to drill holes in my tail light assy. I just didn't think this was a very elegant solution.
Its pretty cramped and I am not sure I could find a good spot to drill anyway. Sort of depends upon your situation.
I am NOT necessarily suggesting anyone do what I did, especially if you do not feel comfortable hacking your vehicles wiring. It was pretty simple and clean for me, it does take some time however. I called my dealer and verified this would not effect the electrical system.
Good luck ... John

Yahoo Message Number: 16780 (http://groups.yahoo.com/neo/groups/Country-Coach-Owners/conversations/messages/16780)I could not agree with you more .... Drilling holes in the tail light assembly is not a very elegant solution. My Tahoe was only 2 weeks old at the time and I was very concerned. The dealer that installed my Blue Ox tow bar told me that was the preferred method so .... "what do I know" Go for it. I found out later that the diode package that Camper World sells was a better solution. All in all, the drilled bulb sockets worked fine until the CC. I suggested converting my Tahoe to the diode system while at Camper World, and was told that would not resolve my problem. Guess I might have to address this problem directly to Country Coach. Seems there should be some simple solution without removing the control module permanently.
I really liked your diagram on the diode installation ... you obviously have an electronics background. How difficult would it be to add another diode and wire from the tow connection, directly to the vehicle wiring to act as a charging circuit? I use a Brake-Pro and on a long run tend to deplete the battery in the Tahoe. (Happened only once, but was very embarrassing to pull into a park and have the thing just moan when I hit the key.)
