Why Choose a Trailer Vision 12-Pin Plug?
Trailer Vision 12-pin plugs offer superior durability compared to more common brands. The stainless steel screws and ferrules used in these plugs are stronger and more reliable than traditional brass components, which can break when tightened firmly.
A useful tip is to spray WD-40 on corroded terminals to temporarily restore electrical conductivity. However, this is only a short-term fix. For long-term reliability, it is best to invest in a high-quality set of LED trailer plugs and sockets.
Benefits of a 12-Pin LED Plug and Socket
- Increased current-carrying capacity
- Easier identification of connections via LED indicators
- Improved weather resistance
- Compatibility with LED lighting systems
If you are towing a trailer, always ensure you are using the correct electrical connector. While a 12-pin LED plug and socket suits most trailers, it is advisable to check the trailer’s owner’s manual for confirmation.
Choosing the Right Plug
When selecting a 12-pin LED plug and socket, consider:
- The type of trailer being towed
- The electrical accessories requiring power
- The environmental and weather conditions
- Your available budget
Common Problems with Trailer Plugs
- Corrosion of terminals
- Water ingress
- Dirt ingress
- Cable separation from terminals
A major cause of connection issues is poor or unsoldered wiring at the plug terminals or trailer lights. To prevent this, twist the cable ends, solder the copper tips, insert them into the ferrules, and tighten securely.
Build Quality and Design
Most standard pin connectors are made from brass or low-quality brass alloys. Trailer Vision addresses this issue by using stainless steel screws combined with plated brass terminals, improving durability and electrical contact.
LED Indicator Functions
Trailer Vision incorporates LED indicators to assist with diagnostics:
- Pin 8: Red LED indicates the breakaway charging circuit
- Pin 5: Blue LED monitors the breakaway battery circuit
Testing the Breakaway Battery
- Disconnect the trailer plug from the vehicle.
- Pull out the pin in the breakaway switch to activate the electric braking system.
- The blue flashing LED on the trailer plug should illuminate, indicating the breakaway battery is supplying power.
- The amber light on the breakaway battery shows the battery’s charging status.
