OVERCOMING WIRING GREMLINS By Mark Penlerick Blue Ox Towing Products The popularity of towing an automobile behind a motorhome has increased by leaps and bounds over the last 10-15 years. Unfortunately, the “gremlins” associated with wiring two vehicles together have thrived even more bountifully. As most of you know, working with automotive wiring, especially the combination of two vehicles, can really test the patience of even the most skilled technicians. Blue Ox has compiled and created some of the most common wiring schematics, and troubleshooting tips concerning wiring a vehicle to be towed four wheels down. First of all we should briefly visit the legal issues behind wiring a vehicle to be towed. Every state and Canadian province requires lighting on the rear of a towed vehicle that is controlled by the towing vehicle. This includes taillights, brake lights and turn signals. These lighting laws are very similar in nature to trailer towing laws. There are basically three ways of wiring a vehicle for towing. The first way of accomplishing rear lighting is a light bar (BX8834). This is an apparatus containing lights with red lens’ usually strapped or magnetically adhered to the top or trunk of the towed vehicle that is hard wired into the electrical system of the motorhome. This system is seldom used today due to the inconvenient nature of its design. The most popular method utilized over the last few years is to use diodes (BX8847 BX8811) to interface the two vehicles wiring platforms together. The cleanest, least intrusive and quickest growing method is referred to as the bulb and socket (BX8869). Diodes “Just what the heck IS a diode and why do I have to mess with them,” is a very common question. A diode is nothing more than a one-way valve that allows electricity to flow through in one direction. When combining two vehicles’ wiring systems together it is very important to protect both vehicles from the possibility of electrical feed
