Understanding the "6 Way Trailer Plug To 7 Way Wiring Diagram" is crucial for anyone who tows a trailer. Whether you're upgrading your trailer's electrical system or troubleshooting a connection issue, knowing how these different plug types translate is essential for safe and functional towing. This guide will break down the "6 Way Trailer Plug To 7 Way Wiring Diagram" to make the process clear and straightforward.
Understanding Your Trailer Plug: 6 Way vs. 7 Way
Trailers require electrical connections to power their lights, brakes, and other accessories. The most common types of connectors are the 6-way and 7-way plugs. A 6-way connector typically provides basic functions like running lights, turn signals, brake lights, and ground. A 7-way connector, on the other hand, offers all these functions plus an additional pin for auxiliary power, which can be used for things like charging a trailer battery or powering internal trailer electronics. When you're dealing with a "6 Way Trailer Plug To 7 Way Wiring Diagram," you're essentially looking at how to adapt or integrate these two systems. The importance of a correct wiring diagram cannot be overstated; incorrect wiring can lead to trailer lights not working, malfunctioning trailer brakes, or even damage to your vehicle's electrical system.
Here's a breakdown of typical pin functions for each:
-
6-Way Round:
- Pin 1: Ground
- Pin 2: Electric Brakes (if applicable)
- Pin 3: Tail/Running Lights
- Pin 4: Left Turn/Stop Lights
- Pin 5: Right Turn/Stop Lights
- Pin 6: Reverse Lights (often not used on all trailers)
-
7-Way RV Blade:
- Pin 1: 12V+ Battery Power
- Pin 2: Electric Brakes
- Pin 3: Ground
- Pin 4: Tail/Running Lights
- Pin 5: Left Turn/Stop Lights
- Pin 6: Right Turn/Stop Lights
- Pin 7: Reverse Lights
The transition from a 6-way to a 7-way system often involves adding the auxiliary power circuit. This might mean you have a trailer that was originally wired for a 6-way and you're installing a 7-way plug on the trailer, or you have a vehicle with a 7-way socket and need to connect a trailer with a 6-way plug. A "6 Way Trailer Plug To 7 Way Wiring Diagram" will illustrate which wire from your existing 6-way setup corresponds to the new pin on the 7-way connector. For example, the ground wire from the 6-way might be used for the ground pin on the 7-way, and the new 7th pin would need a dedicated wire run from your vehicle's 7-way socket to provide that auxiliary power.
It's important to note that some older 6-way connectors might have different pin assignments. Always double-check the specific wiring on your trailer and vehicle. Here's a simplified table illustrating the common crosswalk:
| 6-Way Pin | Common 7-Way Function |
|---|---|
| Ground | Ground |
| Electric Brakes | Electric Brakes |
| Tail/Running Lights | Tail/Running Lights |
| Left Turn/Stop | Left Turn/Stop |
| Right Turn/Stop | Right Turn/Stop |
| Reverse Lights (optional) | Reverse Lights |
| (No direct equivalent) | 12V+ Battery Power (Auxiliary) |
When working with a "6 Way Trailer Plug To 7 Way Wiring Diagram," pay close attention to the wire colors. While standards exist, they can sometimes vary. The goal is to ensure each function is connected to the correct terminal on the new plug.
