The Mobi (Mobi-Jack) Metal 7-Pin Male Trailer Plug is a heavy-duty electrical connector used to link a vehicle’s lighting system to a trailer, caravan, or horse box. Unlike plastic versions, the metal housing is designed for superior durability in harsh towing environments, making it a preferred choice for agricultural and off-road use in South Africa.
Key Performance Features
- Durable Aluminium Body: The rugged metal housing provides high resistance to impact and protects the internal wiring from road debris.
- Corrosion Resistance: The metal is typically treated or alloyed (Aluminium/Zinc) to resist rust, which is essential for long-term outdoor exposure.
- High Conductivity: Features high-quality brass pins that ensure a stable electrical connection, reducing flickering or failure of trailer indicators and brake lights.
- Rubber Weather Shroud: Includes a rubber rear boot that seals the cable entry point, preventing water and dust from entering the plug and causing short circuits.
- Standard SABS Configuration: Follows the standard 12N wiring pattern used across South Africa, ensuring compatibility with almost all local towbar sockets.

Standard 7-Pin Wiring Guide
If you are replacing an old plug, the standard South African wiring colors are:
- Yellow (L): Left Indicator
- Blue (54G): Fog Light / Aux 12V
- White (31): Earth (Return)
- Green (R): Right Indicator
- Brown (58R): Right Tail & No. Plate Light
- Red (54): Stop/Brake Lights
- Black (58L): Left Tail Light
Installation Tips
- Strip Carefully: Only strip about 5mm of insulation from the wires to prevent stray strands from touching adjacent pins and causing a short.
- Use Ferrules: For a professional, vibration-resistant connection, crimp small bootlace ferrules onto the wire ends before inserting them into the screw terminals.
- Dielectric Grease: Apply a small amount of electrical contact grease (or even a spray of Q20) to the brass pins to prevent oxidation over time.
