Making your own trailer wire is not that difficult if you know the steps, the components, and you have a visual illustration that will guide you all the way into the perfect wiring. We have a collection of printable trailer wire diagram to give you. When you are rewiring or making a new wire for your trailer, you’ll need to know the type of the wiring. Check out the following Trailer Wire Diagrams for a quick reference to the wiring system.
There are 4, 5, 6, and 7-way pin trailer diagrams that we have on this page. In the 7 pin Trailer Wire Diagrams, find the exact plug just like the diagram and match the functions, not the colors. There are two types of 7-way connectors: with flat pins or blades, and round pins. The round pin style is very rare. The 7-way with flat pins is very common and often found on newer trucks and SUVs. Check out the following 5 and 6 pin trailer wire diagrams below.
Take some notes that when you wire a trailer with a 7 pole connector, there’s one additional circuit than the 6 poles. This circuit is a back-up or also known as an auxiliary feed. There are several standards for trailer wiring, and each diagram is made for a different type of trailer. Match the diagram with the type of pin that you will use.
All of the diagrams provided above are free to download and print. Check out our other wiring diagram and make sure to share this post to your friends who are wiring as well! Find more update of the newest diagrams on our site!
