Car Dolly / Wiring Question

[Darel]

I bought a used car dolly to pull behind my 28' Argosy MH. I need to know how to wire the lights on the vehicle that I am going to tow. Where can I find this information?
Thank You,

I haven't done it, but would think you need to install a connector in the wiring to the towed vehicle's tail lights to disconnect them from the vehicle, and connect them to the motor home. I have a set of add-on suction cup mount lights that are used on the back of towed vehicles that do not require wiring into the towed vehicle's wiring that I use with my tow dolly.

Darel,

With a car dolly you shouldn't need to do any wiring on the vehicle being towed. Normally car dollies have lights mounted on the fenders. If your car dolly doesn't have them I'd go buy a set of trailer lights and figure out a way to mount them. The wiring information comes with the trailer light kit. See the picture below for reference:



One of the advantages to this method is you can tow different vehicles without having to mess with their wiring.

Seems like a lot of folks that wire their car lights to work with the Moho lights end up with all kinds of shorts and such. Your tow dolly is already lit. By law that is enough, however I have a set of lights that sit in the rear window of our VW Jedda when we tow it. I run the wire from the Moho through the grill and then into the passenger compartment. Then over the seats to the back window. Just a little extra safety precaution.

If you realy want lights at the rear of a car in tow I would agree with bkanler and cooperhawk and make or purchase a light bar that is wired directly to your dolly lights and can be attached to the car. If you chose this route make sure the lights are LEDs and thus will have a minimal current draw on the trailer wiring.

Attempting to wire into most newer cars is not an easy task as the manufactures have made them as complex as possible with a myriad of relays.

I want to that everyone that responded.

The car dolly that I bought is only equiped with running lights, but it shouldn't be too hard to buy a tail light kit and mount them on there.

Where would I be able to pick up a light bar or suction cup mounted lights for the rear of my vehicle?

Also, what type of plug conversion do I need to go from Moho (1977) to the standard trailer lights plug?

Thanks again,
Darel

Darel,

Don't know what type of plug you have on the motor home, but Northern Tool has all kinds of plugs, sockets, and light sets. Harbour Freight also has bargains on light sets, including suction cup sets.

Wal Mart, Auto Zone, Pep Boys, or any other auto supply should have anything you need.

If your truck is not now wired with a brake light signal to the rear you will have to run a wire back for that.

I think I mention before but if not make sure any system you buy is LED and not standart bulbs. I say this because sometimes the additiona of an additional load on the trucks turn signal system will cause problems and it not worth finding out. Besides they last for ever and are much brighter.
