Trailer Hitches, Wiring & Brake Controllers in Terrell, TX
Rated to the truck. Wired to the trailer. Done in one place.
A hitch is three things that have to work together: something to pull with, wiring that tells the trailer what the truck is doing, and a way to work the trailer's brakes from the driver's seat. We fit all three and quote the parts and labor as one number.
Receiver hitches
A receiver bolts to the frame, not the bumper, and gives you a square tube to drop a ball mount into. It is the foundation for everything else: a bike rack, a utility trailer, a cargo carrier or a boat. Classes run from light-duty up to heavy, and the right one is matched to the trailer's loaded weight rather than what it weighs empty.
Most of the trucks that come through here are pulling equipment trailers, stock trailers or a boat, which puts them in the middle of that range. We carry Curt and B&W, and we will tell you plainly if the hitch you are asking for is more than the job needs.
Trailer wiring
Wiring is what makes the trailer legal and visible. A 4-flat connector carries running lights, turn signals and brake lights. That is enough for a small utility trailer with no brakes of its own. A 7-pin adds three things that matter as soon as the trailer gets heavier: a circuit for the trailer's electric brakes, a reverse light feed and a charge line that keeps a breakaway battery topped up.
On a truck with a factory tow package the plug is usually already there and it is a matter of connecting to it properly. On a truck without one, we run a harness that ties into the lighting circuits the way the manufacturer intended, rather than splicing into whatever is nearest. The difference shows up three winters later, when the splice corrodes and the trailer's left turn signal stops working on a wet Tuesday.
Brake controllers
A brake controller lives in the cab and operates the trailer's brakes. Without one, a loaded trailer is stopping the truck instead of the other way round. Texas requires working brakes on a trailer over 4,500 lb gross, with one narrow exemption below 15,000 lb for a trailer kept under 30 mph. Anything at gooseneck or Fifth Wheel weight is past both lines.
There are two kinds worth knowing about. A time-delayed controller applies a preset amount of trailer brake every time you touch the pedal, ramping up over a set period. It is cheaper and it works, but it brakes the same way whether you are easing up to a light or standing on it.
A proportional controller reads how hard the truck itself is decelerating and matches the trailer to it, so the rig slows as a single unit. If you tow a few times a year, time-delayed is fine. If you tow for work, buy the proportional one.
Some late-model trucks have an integrated controller built into the dash from the factory. Where that exists, it is usually the best option because it talks to the truck's own brake system. Where it does not, an aftermarket unit mounts under the dash within reach of your right hand. We wire it properly and set the gain with you before you leave. A controller set wrong is worse than no controller at all.
What we need to know
Year, make, model and whether the truck already has a factory tow package. If you know the trailer's loaded weight and whether it has electric brakes, that settles the rest. For heavier towing, look at gooseneck and Fifth Wheel hitches, and if the back of the truck squats under the load, air bags level it back out.
Common questions
What class of hitch do I need?
It depends on the loaded weight of what you are pulling, not the empty weight. Tell us about the trailer and roughly what goes on it, and we will match the class to the job. A hitch rated for the trailer you have now is worth less than one rated for the trailer you will buy next year.
Do I need a brake controller?
In Texas, a trailer over 4,500 lb gross weight must have working brakes. The one exemption, for trailers under 15,000 lb kept below 30 mph, rules itself out the moment you get on a highway. Electric trailer brakes need a controller in the cab to operate them. Beyond the law, anything heavy enough to push the truck at a stop sign needs one, and gooseneck and Fifth Wheel loads do.
What is the difference between proportional and time-delayed?
A time-delayed controller applies a fixed amount of trailer brake whenever you press the pedal. A proportional one senses how hard the truck is slowing and matches the trailer to it, so the rig stops as one piece. Proportional costs more and is worth it if you tow often.
My truck has a factory tow package. Do I still need anything?
Often just the controller and sometimes an adapter. A factory package usually means the wiring and the receiver are already there, and an integrated controller can be added that works with the truck rather than around it. Bring it in and we will look at what is already fitted.
What is the difference between 7-pin and 4-flat wiring?
A 4-flat carries lights only — running, turn and brake. A 7-pin adds trailer brakes, reverse and a charge line for a trailer battery. If the trailer has brakes or a breakaway kit, it needs the 7-pin.
How long will a hitch installation take?
A straightforward receiver and wiring is usually a same-day job. Adding a brake controller means running a wire into the cab and finding a clean place to mount it, which adds time. Call with the year, make and model and we will tell you what to expect.
