Electrical Requirements  

It is important to ensure that the towing electrics meet the operating requirements of ATC to ensure the system works correctly during travel.

ATC requires power direct from the towing vehicle electrics and needs a constant 12 volt supply from either Pin 9 on 13-pin or Pin 4 on 12S 7-Pin electrics. Use a multimeter to confirm that the correct pin position is providing a constant 12V supply regardless of whether the engine is on or off.

ATC also needs a good earth connection and a 20 amp fuse is required for the constant 12V supply to Pin 4 on the 12S socket. If only a single fuse is fitted to supply both pins 4 and 6 on the 12S wiring, the power supply capability of the installation must be checked and a minimum fuse rating of 25 Amps must be used.
