9.1.18 Dashboard ignition key
The dashboard ignition key is next, this usually has two pairs of terminals on it, we need to use one of each.
The spare terminals could be used to power other accessories if required from either a Permanent or Ignition
supply. The Ignition key supplies the steering ignition key and acts as a master key switch.
The terminals can be connected either way around.

9.1.20 Fuel gauge
Next fit the Fuel gauge. This needs to be wired through the voltage regulator (the small metal box with two
pairs of terminals) as fluctuating voltage will cause an unstable fuel reading. The fuel gauge can be wired
either way around.

9.1.21 Windscreen wiper switch
Under the fuel gauge is the windscreen wiper switch, like the heater fan switch only single speed switches
are available to match SS100 pull switches, options are:
1) Choose which speed suits you best and only connect that wire.
2) Use a two-speed dash switch, at present no new switches are available to match the SS100 pull
switches.
3) Wire up a two-position changeover switch behind the dashboard, wiring details below, this way the
dash pull switch will turn on the wipers and the speed set by the extra hidden switch.
