THIS PAGE HAS NOTHING TO DO WITH BOWLING


BUT I HOPE THE CONTENTS MAY PROVE USEFUL TO SOME OF YOU ESPECIALLY
ANY STUDENTS LOOKING FOR THESE TYPES OF FORMULA FOR HOMEWORK,
OR IF YOU NEED TO WIRE UP YOUR CAR FOR TOWING A CARAVAN OR TRAILER.

! SHOULD YOU EVER NEED TO WIRE UP A CAR TRAILER SOCKET !


These are the connections for the " BLACK " 7 pin Socket.
AT THE BACK OF THE " BLACK " SOCKET EACH CONNECTION PIN IS NUMBERED FROM 1 TO 7.
TO WIRE THIS EXTEND WIRES FROM EACH OF THE CARS CORRESPONDING LIGHTS,
USE SNAP CONNECTORS TO MAKE THE JOINTS, AND THE SAME COLOURED WIRE ,
THEN CONNECT INTO THE CORRESPONDING TERMINAL AT THE BACK OF THE SOCKET.

NOTE : " THE TRAILER LIGHTS PLUG USESES THE SAME COLOUR CODE AND NUMBERING."

TO WIRE UP THE " GREY " ACCESSORY SOCKET


BY WIRING UP THE " GREY " SOCKET YOU WILL BE ABLE TO CHARGE THE CARAVANS BATTERY
AND RUN ANY OF THE ONBOARD EQUIPEMENT WHILST YOU ARE TRAVELLING.

AT THE BACK OF THE " GREY " SOCKET THERE ARE 7 CONNECTIONS NUMBERED 1 TO 7,
FOLLOW THE WIRING DIAGRAM AS SET OUT BELOW. TO CONNECT INTO THE EXISTING CIRCUIT
USE SNAP CONNECTORS AND SEVEN CORE COLOURED CABLE TO EXTEND ALL SUPPLIES FROM
THE CARS POWER SUPPLY TO THE " GREY " SOCKET.
