Trailer Wiring & Brake Controllers in Hillsboro, KS
The short answer
Trailer wiring connects your truck's lights and brakes to the trailer, and a brake controller is the dial in the cab that tells the trailer's electric brakes how hard to work.
If the lights stay dark or the trailer pushes the truck when you stop, one of those two is the reason. Think of pulling a loaded stock trailer down US-56 when the car behind cannot see your turn signal, or every head of cattle leaning forward as you slow for a stop sign. Moxie installs and repairs trailer wiring and brake controllers in Hillsboro and tests the whole connection before you hook up, so bring it in, or we will come and get it.

We test the truck and the trailer separately first. A trailer that will not light up can have its fault on either side of the plug, and testing both stops us replacing wiring that was never the problem.
We fit the connector your trailer actually uses. Smaller utility trailers usually use a four-pin plug for lights only, while stock trailers, campers and anything with electric brakes use a seven-pin plug that also carries brake power and charging.
We install a brake controller that suits how you tow. We fit Tekonsha, CURT and REDARC, which all do the same basic job of applying the trailer's brakes as you slow down. We mount it in the cab where you can reach it, wire it into the truck, and show you how to set it for the load. Too little braking and the trailer pushes you, and too much locks up the trailer brakes.
We finish with the trailer hooked up. Every light and the trailer brakes get checked with the trailer connected before it goes back to you. You see the parts and the price before any work starts, and nothing is done until you approve it.

- We test the trailer on its own, so we know whether its lights and brakes work.
- We check the grounds, fuses and relays, since those cause most of the odd faults.

Trailer wiring and brake controller questions we hear every week
Why are my trailer lights not working?
The most common reasons are a corroded plug, a bad ground wire or a blown fuse in the truck's towing circuit. A ground fault often makes lights flicker or behave strangely, such as one turn signal lighting both sides. We test the truck and the trailer separately, so we can tell which side of the plug has the problem.
Do I need a brake controller?
You need one if your trailer has electric brakes, because the controller is what tells those brakes to work. Many larger trailers have them, including a lot of stock, flatbed and camper trailers. Your trailer's paperwork, or a look at the axles, will tell you. If you are not sure, text us a photo and we will help you check.
How much does it cost to install trailer wiring or a brake controller?
The cost depends on your truck, whether it already has some factory towing wiring, and which plug and controller you need. A truck with a factory tow package is often a quicker job. Call or text us the truck and trailer details, and we will give you a price before any work starts.
