Towing Electrical & Wiring

T-Connectors, Wiring Adapters, Harness Extension

Towing a trailer is not a trivial task. Once you get the hitch and ball attached, you still need to marry the trailer's electrical system to the tow vehicle's. Most trailers have brake lights, running lights, and turn signals. However, they also have electric brakes, breakaway boxes, batteries that need to be charged, as well as interior lights and accessories up to and including refrigerators powered through the trailer hitch connector.

There is a number of standardized trailer connectors, such as 4-pin flat, 5-pin flat, 6-pin square/round, and 7-pin round. The simplest 4-pin system is used for small trailers, and has one ground pin, and one pin each for the left and right turn signals, and one for the running lights. The 5-pin system adds a wire from the backup lights, which is used not only to activate the backup lights, but also to lock out the hydraulic brakes on trailer with surge brakes.

Six-pin square connectors are generally found on RVs to make a 12-volt circuit available from the tow vehicle to run accessories or charge a battery. Six-pin round connectors are common on horse trailers. If the trailer has electric brakes, the 6th circuit is used to actuate them. Seven-pin connectors are most commonly found on new vehicles that are prewired for towing. In this case, the 7th circuit is used to run the backup lights. Fortunately, CARiD has adapters to allow you to plug almost anything into almost anything and have it all work out.

Want to check out the tow vehicle wiring before you head out to pick up the trailer? We have test lights that plug right into the trailer connector, illuminating LEDs for every function. Anyone familiar with trailers knows they constantly have problems. We have a full line of trailer replacement lights and even complete wiring harnesses to repair them. Your boat trailer is intermittently submerged in water, therefore, expect to replace the light fixtures periodically as the electrical contacts and reflectors corrode.

One great safety feature on larger trailers is the breakaway box, which has a small battery and a lanyard that leads to the tow vehicle. If the trailer hitch pops off the ball and heads off on its own, the battery activates the trailer brakes. Yes, we have breakaway boxes as well as all of the electric brake parts from full systems to individual parts and batteries. Those batteries are set to recharge from the tow vehicle, but eventually they'll go bad. Yes, we have them here at CARiD too.

Installation took minutes and I was towing away. Exactly what I ordered.
