Is a trailer brake controller necessary equipment?
Question by Jake: Is a trailer brake controller necessary equipment?
I am looking into putting a trailer hitch on my truck so that we can move. But I get a little bit confused when the mechanic starts talking about electrical equipment. Do I want a “round 7″ or a “flat 4″ or both? And is it necessary to also install a trailer brake controller?

The need for trailer brakes depends on the tow vehicle and the trailer.
In most instances of light duty trailer towing such as a typical trailer obtained in a rental facility, a additional brakes on the trailer aren’t necessary. The key phrase here is “light duty.”
If the trailer you have in mind has prompted your mechanic to recommend the installation of trailer brake electrical equipment in your truck and you only plan on using it once to move, your best bet might be to simply rent a larger, enclosed truck designed for this purpose.

It depends on how heavy the trailer you’re towing is. Most states require electric brakes on any trailer capable of carrying 3,000 Lbs or more. If the trailer has electrical brakes you need a brake controller in the pickup. If the trailer doesn’t have brakes the controller isn’t needed. Just remember that the cars brakes will have to work harder to stop all that weight if you tow with no trailer brakes. It can be real scary trying to stop with a heavy load pushing you.
Depends on if the trailer your using is equipped with brakes, if so then yes you need a brake controller and a 7 pin connector, if not all you need is a 4 pin, which only operate the trailer lights, the extra 3 on a 7 pin are for a ground which a 4 pin makes through the hitch, which is why sometimes you see the lights flickering on some trailers, a 12 volt power supply to charge your emergency break away battery and a power supply coming from the controller. and if you plan on renting one ask to see if it has electric or surge breaks if surge all you need is a 4 pin, but make sure they explain the back up feature to you in case you have to back it in somewhere
1. A simple flat 4″ will be all that you need but before you do anything check your truck because depending on the year, make and model you may already have one installed from the factory…..
2. Electronic trailer brake controllers are important tools when towing trailers that are too heavy for your vehicle to stop effectively. An electronic trailer brake controller will ensure your vehicle and trailer stops smoothly and in a proper distance……..
Lightweight trailers (3000 lbs and under) do not require trailer brakes. Trailers over 3000 lbs are required to have brakes.
There are three types of trailer brakes. There are air brakes, which are commonly found on trucks and tractor trailer rigs. They are not used on the type of trailer you are talking about.
There are surge brakes, which have a hydraulic control mounted on the trailer tongue. When the towing vehicle slows, the momentum of the trailer pushes against the ball, and this activates the trailer brakes, These are common on rental trailers (U-haul) and some boat trailers.
There are electric brakes. These are controlled by an electric brake controller, and are wired into the vehicle brake light switch. When you hit the brakes,power is sent to the electrical brake actuators on the trailer and the brakes are applied. The trailer brake control can be adjusted to provide the right amount of braking power being applied to the trailer under different conditions. You want less braking on an empty trailer than a loaded one.
If you are going to be renting a trailer to move, you do not need a brake controller. A 4 flat wiring connector will provide the wiring for the lights that you will need, you will have to buy an adapter seeing as the rental trailers have no connectors on them. If you are going to buy a trailer, decide on the trailer (so you know what type of brakes you have) and then have the needed wiring and controller installed.
The purpose of a truck is to do whatever you ask of it. For a lightweight trailer all you need to connect are the trailer lights, a flat four connector. For bigger trailers you need trailer brakes, a brake controller, and a round seven connector.
You can get a plug-in adapter to go from your round-7 to a flat-4 if you haul a light trailer.
You cannot go from a flat-4 to a round-7 with brakes without re-wiring the truck.
Do it right, do it once.
do not know where your moving to or from, but in new york state any trailer over 1000 pounds gvwr, has to have trailer brakes by law. most other states are 3000 pounds.
You’ll have to check with your state the the states you are traveling through. Most of the states I’m aware of require trailer brakes at 2,200 lbs or higher. (My camper grossed at 2,000 lbs and wasn’t required to have brakes. That’s presuming that the tow vehicle is large enough to tow the trailer. There’s no way I would tow a 2,000 lb trailer with a car that weights 1,500 lbs.
The round 7 or flat 4 are the types of connectors between the towing vehicle and the trailer. If you don’t need trailer brakes, you’ll use a flat 4. The round 7 has extra wires for electric brakes on the trailer.
