The Carpoint 7-core trailer cable can be connected to a trailer or caravan 7-pin plug connector. The 7-pin system transmits all the car’s basic electrical functions. Each wire is 1mm2 in diameter and has its own colour;

• white (earth) 
• yellow (left indicator) 
• green (right indicator)
• brown (right rear light/position light and number plate)
• black (left rear light/position light)
• blue (continuous power supply)
• red (brake lights) The open cable ends are easy to fit to a 7-pin plug. The Carpoint trailer cable is 50 metres in length.
