If you’ve ever owned a trailer or have used one for hauling purposes, you probably know how important it is to have a reliable wiring system. A good wiring system ensures proper functioning of the trailer’s lights, brakes and other electrical components, making it safe to drive on the road. In this article, we’ll be discussing the 6 round to 7 blade wiring diagram, a conversion that’s common for many towing systems. We’ll go through the process of converting your trailer’s existing wiring system, step by step.
What is a 6 Round to 7 Blade Wiring Diagram?
A 6 round to 7 blade wiring diagram is a diagram that shows the electrical connections needed to convert a 6 round trailer connector to a 7 blade trailer connector. The conversion is needed when your towing vehicle has a different wiring system than your trailer. The 6 round connector has six pins that are designed for basic trailer wiring, while the 7 blade connector has seven pins that can accommodate a wider range of electrical components, such as brakes and reverse lights.
Why Do You Need to Convert to a 7 Blade Connector?
If you have a newer towing vehicle, it most likely has a 7 blade connector, while older trailers typically have a 6 round connector. Converting your trailer’s wiring system to a 7 blade connector ensures compatibility with your towing vehicle’s wiring system. This also allows you to use more advanced electrical components, such as brakes, backup lights, and more.
What Do You Need to Convert to a 7 Blade Connector?
Converting from a 6 round to 7 blade wiring system requires a few tools and components:
| Tools and Components | Functions |
|---|---|
| Wire strippers | To strip the wires on both the trailer and towing vehicle side |
| Wire cutters | To cut wires to the correct length |
| Crimping tool | To crimp the wires together |
| 7 blade connector | The actual connector unit that will replace the old 6 round connector |
| Electrical tape | To cover the wiring connections after crimping |
How to Convert from 6 Round to 7 Blade Wiring System: Step-by-Step
Follow these steps to convert your trailer’s wiring system from 6 round to 7 blade connector:
Step 1: Identify the Wiring System
Before you start the conversion, identify how the trailer’s current wiring system is set up. You’ll need to know what each wire does, where it’s located, and how it’s connected. Refer to the wiring diagram for your trailer and towing vehicle to ensure proper connections.
Step 2: Strip the Wires
Using wire strippers, strip the insulation off the wires on both the towing vehicle and trailer sides. You’ll need to expose at least 1/2 inch of the wire’s bare copper core.
Step 3: Cut the Wires to the Correct Length
Cut the wires to the correct length based on the wiring diagram. Make sure the wires are long enough to reach the connector, but not too long that they become tangled or damaged.
Step 4: Crimp the Wires
Using a crimping tool, crimp the wires together according to the wiring diagram. Make sure that each wire is correctly connected to its matching wire on the other side. Cover the connections with electrical tape to prevent any accidental disconnections.
Step 5: Install the 7 Blade Connector
Attach the 7 blade connector to the trailer’s wiring system using screws or bolts. Make sure that the connector is securely attached and the wires are not pinched or frayed.
Step 6: Test the Wiring System
Test the wiring system to ensure it’s working properly. Turn on the towing vehicle’s lights, apply the brakes and turn signals, and ensure that each component of the trailer’s wiring system is working correctly.
FAQ’s About 6 Round to 7 Blade Wiring System
Q1: What is the difference between a 6 round and a 7 blade connector?
A 6 round connector has six pins that are designed for basic trailer wiring, while a 7 blade connector has seven pins that accommodate a wider range of electrical components, such as brakes and reverse lights.
Q2: Can you use a 6 round connector with a towing vehicle that has a 7 blade connector?
Yes, you can use a 6 round connector with a towing vehicle that has a 7 blade connector, however, you won’t be able to use advanced electrical components like brakes and reverse lights.
Q3: How much does it cost to convert from a 6 round to 7 blade connector?
The cost of converting from a 6 round to 7 blade connector depends on the components you need and how much you can do yourself. A conversion kit may cost between $20-$50, while a professional installation may cost upwards of $100.
Q4: Can I convert a trailer with a 4 pin connector to a 7 blade connector?
Yes, you can convert a trailer with a 4 pin connector to a 7 blade connector. However, you’ll have to run additional wiring to accommodate the extra electrical components.
Q5: What happens if my trailer and towing vehicle have different wiring systems?
If your trailer and towing vehicle have different wiring systems, you’ll need to use an adapter or converter to ensure compatibility. An adapter allows you to use a 7 blade connector on a towing vehicle with a 6 round connector, while a converter allows you to use a 6 round connector on a towing vehicle with a 7 blade connector.
Conclusion
Converting from a 6 round to 7 blade wiring system is essential if you’re using a newer towing vehicle with a different wiring system than your trailer. This conversion will ensure compatibility and allow you to use advanced trailer electrical components such as brakes, backup lights, and more. Follow the steps outlined in this article, and you’ll have your trailer wired for success in no time.
