Wiring for tow car
Yahoo Message Number: 48394
I am having my car set up to tow before I go out to pick up my new mid-bath.  ( I know I can't tow for 1000 miles) We are using the wiring diagram in the Lazy Daze manual.  Has anyone had any experience with wiring that I should know about?

I know nothing about wiring ... but ... my experienced installer had to get an alternate coupler to set up the lights/brakes on my towed 2004 Jeep Wrangler Sahara.  He said the wiring out of my 2004 26.5 MB was "different."

Hi Jo Green is right turn, Yellow is left turn, brown is running lights, white is ground, if you have a 6-pin female plug installed on the back of your new LD then you have 2 wires extra probubly a black wire and blue wire if you buy a 6 wire cable for your toad. The blue is for trailer brakes which you don't need so you could use eather for a charge wire for the toad as if you use a brake buddy and make a lot of stops you will run the toad battery down. If your toad is forign (Nipon) you can buy a majic box from an auto store to convert forign to american wireing. I have found it easeyer to start at the back of the toad where this adapter plugs in or wires in run your cable from this point thru the frame to the front leaving enough slac to get to the back of the LD and leaving enough so you can make the sharp turns without putting stress on the plug.
I hope I haven't completely confused you or frightened you it's really simple after you have done it a dozen times Ho Ho Ho. Good luck, Congrads. etc. I hope you love your LD as much as I love mine.
Sincerely Robert

 I don't know anything about the wiring, either.  However, when we had our Honda Element wired for the ReadyBrute Plus tow bar/brake we had installed, they used the 4-pin connection that came on the Lazy Daze.

I don't know if the difference is in the car or the tow bar system.

Did you go the route of adding bulbs in your Element tail lights?  I gather that is more and more the route many are taking.



 As far as I know, no extra bulbs were added to the tail lights.  Why would this be done?  Do tail lights have sockets for more than the bulbs that come standard in them?

The Motor Home 2005 Guide to Dinghy Towing has the following:

"...it is becoming more common to modify each of the vehicle's tail-lamp assemblies to accept a separate bulb. This bulb is then connected directly to the motorhome, eliminating any connections to the vehicle's existing wiring harness."
 It is done to avoid interference with the dinghy's electrical system.

The wiring package I ordered for our Element is of this type.  (Not installed yet.)

Is there a website that explains or shows how the extra bulbs are installed inside the towed vehicle's tail light housing ?

For safety, I drive with the 2004 26.5 MB's lights on.

 Good for you, Bob! So do I. If more people did that, statistics show, there'd be fewer accidents.

 OK, I see.  We didn't need to have the separate bulb installed because the tow bar/brake assembly we have ( http://www.readybrake.com/readybrute.html ) included a brake circuit disconnect which prevents this "signal override" problem.

Not that I know of.
 Here's a quick summary:  Many LD (and SOB) owners find that "standard wiring" (that is, wiring from the motorhome to the toad, with diodes in the toad to protect it's electrics) yields VERY dim lighting on the back of the toad.  The three popular "fixes" are--
 Buy an auxiliary lighting kit (available at an auto parts store), mount it high up on the toad, and wire it to the MH plug. ( But lights may still be a little dim.)
 Dissasemble the toad tail-light, drill mounting holes for an extra set of lights (either conventional or LED) and run them from the MH plug.  (No ugly extra lights, but lights may be a little dim)
 Install a Draw-Tite (brand) light module in the cabling on the MH, which boosts the weak voltage from the MH and use the toad's standard lighting (but still with the isolation diodes).  (Bright lights with nothing extra on the back)
 I went with solution number one and three for my Suzuki sidekick. (bright lights, mounted up above the bikes on the back of our toad)
 If you search the archives you can find lots of useful info.  Message 44083 (and its follow- ups)  in particular is good.

Hope this helps.  /noel/

I used a Modulite for "Yonder", see:
 http://www.hitchfinder.com/electrical/modulite.htm

for a good explanation. I also found Hitchfinder's prices good and service excellent.

Be aware that with any of these converters that deliver full brightness and do not "load" the LD wiring, it will be necessary to run a positive wire from the Modulite (or whichever brand), forward to a battery source. This wire should be at least 12 GA.

To run this wire on the MB:

To the right of where the existing trailer wiring exits the rear wall above the bumper (under fake wheel cover), drill a suitable hole an inch or two to the right of the existing hole. Angle this hole downward at about a 45 degree angle to avoid hitting existing wiring under the coach. It is best to drill slowly and have a spotter under the coach to make sure you don't hit wiring. (You can also fashion a sheet metal shield to cover existing wire bundle if you are working alone).

If you don't have 12 GA wiring handy, there's a couple of good sources. One is "low voltage lighting direct burial wire" available at Home Depot. They sell it by the foot and it's available
