This article will explain how to make a wiring diagram for a 7 blade trailer plug, which is a common type of trailer plug used on trailers today.

The 7 blade trailer plug is commonly used in North America and Europe. It is often the preferred method of connecting trailers to tow vehicles because it provides a more secure connection. The 7 blade trailer plug has seven pins, each with its own unique function and purpose. In order to make a wiring diagram for a 7 blade trailer plug, we must first have an understanding of the different wires and their functions.

Wires and Their Functions


A 7 blade trailer plug has seven different wires and each one has a specific purpose. The wiring diagram for the 7 blade trailer plug needs to show each wire and its corresponding function. The following is a list of the seven wires and their associated function:


  • Blue Wire – Brake Lights

  • Brown Wire – Tail Lights

  • White Wire – Ground

  • Green Wire – Right Turn Signal

  • Yellow Wire – Left Turn Signal

  • Red Wire – Auxiliary Power

  • Black Wire – 12v Power



Making the Wiring Diagram


Once you have an understanding of the wires and their functions, you will be able to make a wiring diagram for your 7 blade trailer plug. The wiring diagram should include the following information:


  • The position of each wire on the 7 blade trailer plug

  • The function of each wire

  • The color of each wire

  • The location of the 12v power source



It is important to note that some trailers may require additional wires or different configurations depending on their use or purpose. Be sure to double check the wiring diagram for your particular trailer before connecting it to your vehicle.

Connecting the Wires


Once you have made the wiring diagram for your 7 blade trailer plug, you can begin to connect the wires. Start by connecting the white wire to the ground. The ground is typically located on the frame of the trailer or the suspension.

Next, connect the black wire to the 12v power source. This could be either the battery of the vehicle or a separate auxiliary power source.

The remaining wires can be connected in any order as long as they are connected correctly according to the wiring diagram. Make sure to use the correct gauge of wire for each connection, as using the wrong size can cause damage or create a fire hazard.

Testing the Connections


Once all the wires have been connected, it is important to test them to make sure they are functioning properly. Take a voltage tester and use it to test each wire and make sure it is working correctly. If any of the wires do not register on the tester, double check the connections and make sure they are secure.

A wiring diagram is essential for connecting the components of an electrical system. Making a wiring diagram for a 7 blade trailer plug is not difficult once you have an understanding of the different wires and their functions.
