The 2 added pins are for Auxiliary Power and Back-up Lights.
Wiring Schematic Drawing How To Wire AGo to Shop. How To Wire A Trailer...Trailer Wiring Diagram... And More So many wires... So many colors... And, so many kinds of trailer wiring connectors. And, a little more information to make sure I get it right There are several standards for trailer wires, and if you search, youll find a different Trailer Wiring Diagram for each. Each standard has its different purpose, so please dont just make it up as you go. 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. 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. Wiring Schematic Drawing Trial Standards WithThat said, for specific situations, there are industrial standards with different connectors and wire arrangements. It can get confusing, so if you dont already have a specific standard in mind, follow these. Pin Flat Connector At a minimum, all trailers need at least 4 functions: Tail lights, Brake lights, Left Right signals. The most common 4 wire connector is the 4-Pin Flat Connector as shown here. Trailers that use this are usually fairly light weight and dont have brakes or other power accessories. Small utility trailers, light boat trailers, little campers, off-road trailers and many more use this traditional 4-Pin Flat connector. Lighter Duty Trailer (No Brakes) Use a 4-Pin Connector. White Ground (See White Wire Notes below.) 2. Brown Tail Lights, Side Markers and Running Lights (See Brown Wire Notes below.) 3. Green Right Turn Signal Right Brake Light Please see the Trailer Wiring Diagram and Connector Application Chart below. The rest you can ignore. Pin Flat Connector (Round style 5-Pin Connectors also exist.) Trailers with capacity over 3000 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. Wire the first 4 pins (White, Brown, Yellow, Green) just like the 4-pin connector above. Blue Electric Brakes or Hydraulic Reverse Disable (See Blue Wire Notes below.) In the Trailer Wiring Diagram and Connector Application Chart below, use the first 5 pins, and ignore the rest. If your truck has a built-in 7-pin socket, but you only need 5 of the pins. Use the 7-pin connector anyway (see below), and just leave out the last 2 wires. It accomplishes the same thing for 5 wires, but with a connector thats compatible with your truck. The 5-Pin flat connector above is nice for easy handling, but if your vehicle already has a 7-pin, just use it. Its OK, within the standards, to leave out wires for your custom situation. Pin Connector For trailers that have a little more going on electrically, we recommend 7-pin connectors.
