Wiring for your trailer can be as simple as plugging in a premade harness to your truck’s rear lights, totally brainless. If you aren’t fortunate enough to have a truck that we have a t-harness for, well, you may have to splice some wires, no big deal. It seems there are a bewildering number of different trailer connection plugs, from simple flat 4- wire plugs to 7-blade plugs as big as an apple. We have adapters to let you plug almost any trailer into any truck that’s wired for a trailer.
Next problem: your car or truck has separate turn signals and brake lights. Trailers almost always use integrated brake/turn signals. Fortunately, we have adapters that intercept the signals to the trailer lights and make everything blink when it’s supposed to.
