ISO 11446:2004 specifies a 13-pole electrical connector between towing and towed vehicles with 12 volt electrical system. It was developed in 1987 by Erich Jaeger[1] to replace older 7-pin plugs.

13-pin female socket (ISO 11446)

Notes

  1. ^ a b c Pins 3, 11 & 13 must not be joined in the trailer to prevent ground loops
  2. ^ a b Pins 5 & 7 must not be joined in the trailer without a pair of diodes
  3. ^ Pin 12 was assigned prior to 2012; older vehicles could be using this for a different function
