The connector helps you connect the wiring of your primary vehicle with that of your trailer. Connecting these in the correct order will ensure that the trailer lights work perfectly in sync with your primary vehicles. While the black wire connects with the battery, the blue wire connects with the electric brakes, and the white wire is connected with the ground. The green wire connects with the taillights, the yellow wire connects with the reverse lights, and the red wire connects with the left light. The brown wire connects with the right light. In this 7-pin trailer wiring diagram, most of the wire configuration is changed. The other colors remain the same for the other wires and their functionality as well.ħ-Pin Trailer Diagram for Traditional RV Blade The red color has been changed to orange and black to grey. This 7-pin trailer wiring diagram shows that the colors of the wires have been changed for the reverse lights and battery source.

The other wire functionalities and placements are similar to those in a 6-pin trailer diagram where white is for ground, green is for right, yellow is for left, brown is for tail lights, and blue is for electric brakes.ħ-Pin Trailer Diagram for RV Blade with SAE Configuration In this 7-pin trailer wiring diagram, the red wire provides auxiliary power to the trailer while the black wires are shifted to indicate the reverse lights. These different 7-pin trailer wiring diagrams are as follows.ħ-Pin Trailer Wiring Diagram with a Round Prong The 7-pin trailer diagram has three different variations depending on the type of connector in which the wiring configuration is also different. So this wire also serves as the reverse light. The extra wire is connected with the backup lights that help disengage the hydraulic coupler of the trailer when the vehicle starts to reverse this turns off the brakes of the trailer. One pin is used for grounding the other commonly used are for indicating turns, breaks, and that the car is running. It is usually used by vehicles that use hydraulic or surge brakes. These are connected via the 5-Way connector.Ī 5-way connector is used to establish an electrical connection between the trailer and the primary vehicle. The last set of wires (yellow) leads to the left side to indicate the left signal. The fourth wire (blue) is the one that indicates when the brakes are applied. These are also connected to the side to ensure increased visibility. The third (brown) wire is the one that is responsible for the taillights. The second wire (green) to originate from the connector is responsible for the right signal.

In this 5-pin trailer wiring diagram above, you can see that the first wire is the ground wire (white). The different types of trailers are as follows: They are used for transporting goods, materials, boats, camping utilities, etc. The trailer has several applications depending on the user and what kind of services one might be looking for. The minimum output connector is the 4-Way connector, providing electrical output to the trailer's signals and ground and tail lights. To make the trailer’s electric output work, we use different connectors to ensure that depending on the outputs we require. The trailer is attached to the primary vehicle by the appropriate hitch. They can also be recreational vehicles depending on their type.Ī trailer is a separate extension vehicle that needs to be linked with the primary vehicle. A trailer is an unpowered vehicle and is supposed to be towed by another vehicle: SUVs, pickup trucks, or jeeps commonly tow trailers.
