Start by identifying the terminals on your trailer plug. There should be seven in total, each labeled with a number. Refer to your wiring diagram to determine which wire goes to each terminal. This step is crucial for ensuring proper functionality.
Next, strip the insulation off the ends of your trailer wires and connect them to the corresponding terminals on the plug. Use your voltage tester to double-check that everything is connected correctly and that there are no loose connections.
Once you’ve confirmed that all the wires are securely connected, use electrical tape to wrap each connection individually. This will help prevent any moisture or debris from causing a short circuit down the line.
Finally, give everything one last once-over to make sure all connections are secure and tidy. Once you’re satisfied with your work, you’re ready to test out your newly wired 7 blade trailer plug. Hook it up to your vehicle and trailer, and you should be good to go!
With this handy guide, you’ll be able to tackle your 7 blade trailer plug wiring with confidence. Remember to always prioritize safety and double-check your work before hitting the road. Happy towing!
