Alternatively, to fit the digital timer, simply fit the
appropriate screw inside the hole located at the
center of the timer. Both plug into the corresponding
black and clear plugs on the loom.
NOTE
Only one controller can be used at a time.

Controller Connections

The controllers are best installed in a manner that
they can be seen and operated easily to identify
working conditions and also for easy access. The
black and clear plugs connect to the corresponding
plugs on the loom (below). The remaining three-pin
socket on the timer or rheostat control plugs into the
remote control receiver if one is installed. An adaptor
cable may be necessary.

Ambient Temperature Sensor

The external temperature sensor plugs into the
corresponding blue and brown wired socket on the
diagram and should ideally by mounted at shoulder
height when sat down to ensure correct reading of
the air temperature. It should not be mounted in
such a way as to obstruct air flow; like up high, in the
corner of the vehicle cabin or above heat sources.
