This is often overlooked when booking a towbar or can be difficult to understand exactly what your vehicle requires if you have none or very little knowledge. Basic wiring to the sockets and plugs is a rather straightforward procedure, however when you require audible replays and bypass kits to cope with the complicated cars of today, this is when things can start to get tricky.
Luckily for you, we do this day in day out. We are fully conversant with all aspects of towbar wiring and are stockists of ECS, Brink, Westfalia, Witter electric kits who are market leaders in the field of towing and trailer electrics. All towbar electrics we supply have a great reputation for quality and durability. Single 7 pin electrics, also known as 12N towing electrics are needed to power the lighting on a trailer, caravan, cycle carrier or anything you're towing. The single 7 pin electrics power left and right indicator and taillights, fog lights and brake lights.
If you don't require any further power to your towing counterpart, the single 7 pin electrics socket will be your main choice. Twin electrics is a 2 plug system which combines the single 7 pin 12N electrics socket with a 12S electrics socket. You will need twin electrics if you require more power than what a single 7 pin socket can provide on a pre manufactured UK caravan post UK caravans are fitted with 13 pin connectors.
The twin electrics will power everything that a single electrics system powers plus reversing lamp, battery, power supply and fridge. The brown pin 5 in most cases is not used when wiring tow bar electrics and it is important to ensure that the white pin 3 cable is earthed. In some cases a split charge relay might be needed in order for the power to switch divide from charging a leisure battery and the car battery.
This is essentially a 2-in-1 socket, it has all the capabilities as twin electrics in one rather than 2 separate sockets. Conversion leads are available for 13 pin towing electrics to twin 7 pin towing electrics or twin 7 pin to 13 pin towing electrics if your vehicle has a 13 pin socket and your caravan has twin 7 pin towing plugs or vice versa.

Products Electrical Lighting. Catalogues Narva Catalogue. About Narva Who We Are.Many different harness types are used to connect tow vehicles' power sources to the electrical wiring on trailers.
The difference between a 6-pin system and a 7-pin is that the 7-pin has a connection for backup lights. What systems are required by law for your trailer depends on where you live. These state laws are listed in the resource section below. If the loss of the backup lights doesn't present a problem, making the 6-pin connection is easy with the right adapter.
Look at the trailer's 7-pin electrical harness and determine if the electrical connections are flat or round. Flat connections have wide slots for the vehicle's male connectors to slide into.
Round connectors have circular holes for the same connection. Go to a hardware store and select an adapter that joins the two different types of wiring harnesses. Slide the 6-pin side of the adapter into the vehicle's harness by pushing the two together. Slide the 7-pin side of the adapter in the trailer's harness. Test that the trailer's lights respond to the vehicle's systems as appropriate.

And every smart RV owner learns what those wires do, and what the symptoms are when there is a bad connection.
RV Motorhomes will have either a 6-pin or 7-pin connector mounted somewhere near the Hitch for connecting to the towed vehicle. Some of the wiring systems used for connecting a tow vehicle with a TOAD or towed vehicle are simpler than others, but there are standards for all of the connectors and how they are wired.
The standard 4-pin connector is a flat plastic connector, with 3 pins either male or female, and the 4th pin t he op posite sex. The connector shown is for the wiring of the towing vehicle. The pins and their usage are.

So many colors. And, so many kinds of trailer wiring connectors. Where do I start? I need a trailer wiring diagram. And, a little more information to make sure I get it right! Follow these guidelines and make it right! The approach for you depends on your electrical needs. To start, every trailer needs lights — brake lights, turn signals, and tail lights. Some also have side markers and running lights. Brakes probably need electricity too — to actuate electric brakes, or to disable hydraulic brakes when backing up.
The following trailer wiring diagram s and explanations are a cross between an electrical schematic and wiring on a trailer. We recommend these standards because they are pretty universal. That said, for specific situations, there are industrial standards with different connectors and wire arrangements. The most common 4 wire connector is the 4-Pin Flat Connector as shown here.
The 4-Pin connector only has the first 4 items listed. The rest you can ignore. Trailers with capacity over Total Gross Trailer Weight should have brakes. If a trailer has brakes, then it needs a connector with at least 5 pins. The 5th pin, a blue wire, gives power to operate or disable the trailer brakes.
If your truck has a built-in 7-pin socket, but you only need 5 of the pins.Before you tow any trailer, you should make sure it has functional trailer lights. Because installation works related to electricity scary many vehicle owners away, they prefer the experts at trailer shops to have the job done for them instead of trying to figure out how things work.
While the basic configuration is a 4-way flat connector that features one female and three male ends, you may come across connectors with up to seven pins for additional functions that require wiring, including electrically actuated brakes, power source for a winch, etc.
This is the most common scenario. It has three poles for basic functions running lights, turn signals, and brake lights and one pin for the ground.
This connector is commonly found on most light-duty trailers. When wiring trailer lights, make sure to route the harness away from anything that could damage the wires. Trailers longer than 15 feet and heavier than 1, lbs must have a brake system — that means another circuit for hydraulic brakes.
The fifth wire blue is meant for reverse lights; this connection is needed to disconnect the hydraulic trailer coupler or actuator when the vehicle is backing up, thus deactivating the brakes on a trailer.
Apart from providing basic functions, this connector has 2 more ports for electric brake control blue and 12V power supply black or red. Now that you know the types of connectors, you have to determine what you have on your vehicle to make the connection to a trailer. They developed a universal trailer connector that has been used on their vehicles since the s. To determine how to wire up trailer lights, you need to know whether your vehicle has a factory-installed trailer package and whether a plug-and-play T-connector is available for it on the market.
As a matter of fact, the aftermarket offers harnesses to join two connectors of any type. Even if your vehicle is not equipped with a connector, it may have a wiring plug located in the rear. Depending on the model, the location may vary from inside of trunk to under the rear floor panel.
If there are absolutely no provisions for trailer lightsyou are electrically inclined or have a rough idea of how to wire trailer lights, you might consider splicing into your existing wiring. In this case, you will need a set of wiring taps and a pair of pliers. To connect the electric system of your trailer to the vehicle, you will be using special connector.
Above we have describes the main types of trailer wiring diagrams. Below is the generic schematic of how the wiring goes.

Note, that this type of 4-pin connector is less common, that 4-pin flat connector. As a rule, you can find these connectors on the older trailers and older vehicles built in the U. At the moment, neiter tow vehicles nor trailers are equipped with round 4-pin connectors from the factory.
As a rule, 5-Way flat connectors are used for trailers that feature surge brakes or hydraulic brakes. The extra wire, as a rule, is used to power backup lights. When it is plugged, it disengages hydraulic trailer actuator when you reverse, so the trailer brakes are off at that moment. A very good explanation what the black wire in the 7-way connector is for. I couldn't find the explanation in 4 more sites I reviewed.
