Follow the instructions that comes with your trailer tester kit and connect the wiring as according to the SABS standard.

Socket and plug wiring instruction

Use 7 core wire (8mm gauge) Socket South Africa.

1) Yellow - left Indicators

2) Blue - Spare/Fridge

3) White - Earth

4) Green - Right Indicators

5) Brown - Tail Lamps and number plate

6) Red - Stop Lamps

7) Black - Tail lamps and number plate

Note. Pins 5 and 7 are normally bridged.

The Earth. (No 3 – white)

The tow hitch of the van or trailer must be on the tow bar of the vehicle so as to create an efficient earth connection. Terminal no 3 (white) has a wire connected at the socket so as to ensure that the trailer/caravan is also connected, and this white wire must be connected to the chassis of the towing vehicle as well.

The Spare/Fridge. (No 2 – Blue) is used to connect the fridge. A 15 amp fuse connector should be connected as a safety precaution. It is recommended that if you do not feel happy doing it yourself it is then better get a tow bar/trailer specialist to undertake this operation.
