How to Add Magnetic Lights to Vehicle on Tow Dolly


Im towing a car on a tow dolly behind our motorhome .The dolly has electric brakes and lights .I was wanting to put magnetic lights on the car and was wondering if i can splice a four prong hookup for the magnetic lights into the tow dolly wiring or do i need a full seperate plug on the back of the rv for the magnetic lights.Thanks


Expert Reply:

You can certainly just splice the harness from the magnetic lights to the appropriate light circuit wires on your tow dolly instead of adding a new plug on the RV. This setup would activate the magnetic lights just the same as running the wiring to the RV.

To do this I recommend the Optronics # TL21RK that includes a separate 3 foot long 4-Way extension so that you can easily splice into the wires. I have attached a short video demonstration on this kit that you can check out as well.
