If you own a trailer, you need to know how to connect it to your vehicle. One of the most important parts of this process is the wiring. The six-prong trailer plug is a common configuration that can be found on many trailers. In this article, we will walk you through the steps of wiring a trailer plug using a 6 prong connector.
What is a 6 Prong Trailer Plug?
A six-prong trailer plug is a connector that has six pins or blades that are used to transmit signals between a vehicle and a trailer. Each pin or blade serves a specific function and is designed to connect to a particular wire on the trailer. These connectors are designed to work with a variety of trailers, including those with electric brakes, and those that require power to be supplied to the lights.
What are the Six Pins on a 6 Prong Trailer Plug?
The six pins on a 6 prong trailer plug are as follows:
| Pin Number | Wire Color | Function |
|---|---|---|
| 1 | Yellow | Left Turn Signal |
| 2 | Green | Right Turn Signal |
| 3 | Brown | Taillights |
| 4 | White | Ground |
| 5 | Blue | Electric Brakes |
| 6 | Red | Battery Power |
Now that we know what each pin does, let’s move on to the wiring process.
How to Wire a 6 Prong Trailer Plug
The following steps will guide you through the process of wiring a 6 prong trailer plug:
Step 1: Gather Your Tools and Materials
Before you begin, you’ll need to gather the following tools and materials:
- 6 prong trailer plug
- Wire strippers
- Wire crimpers
- Electrical tape
- 12-gauge wire (in the appropriate colors)
Step 2: Prepare the Wires
The first step is to prepare the wires that will be connected to the pins on the trailer plug. You’ll need to strip the ends of each wire, leaving about 1/2 inch of bare wire exposed. Be sure to strip the appropriate amount of wire so that it fits snugly into the connector.
Step 3: Attach the Wires to the Pins
Insert each wire into the appropriate pin on the trailer plug. Use the wire crimpers to secure the wire to the pin. Be sure to crimp it tightly so that there is a good connection.
Step 4: Wrap the Connections in Electrical Tape
After the wires are attached to the pins, wrap each connection with electrical tape. This will help to protect the connection from moisture and ensure that it stays in place.
FAQs
Q: What is the difference between a 4 prong and a 6 prong trailer plug?
A: A four-prong trailer plug is used for basic lighting connections, while a six-prong trailer plug is used for trailers that have electric brakes and require power to be supplied to the lights.
Q: Can I use a 6 prong trailer plug if my trailer only has basic lighting?
A: Yes, you can use a 6 prong trailer plug even if your trailer only has basic lighting. However, you’ll need to make sure that the pins that are not used are sealed with electrical tape to prevent moisture from causing corrosion.
