To avoid any visible extra cables in the engine bay and to keep the dashboard as standard and period as possible, this is the solution I came up with. The power is taken via a heavy duty cable from the fusebox permanent live, together with another cable from the switched live. These run to a relay under the dash and then to the new fusebox. This avoids the power for accessories going through the ignition switch. Two additional relays are used for the heated windscreen and rear screens.
The heated screen, reverse and washer switches are nearest the driver as they are most used. The intermittent wiper is on a two stage switch (same as lights) using original knob. The reverse switch lights up white, the heated screens have separate amber warning lamps and the fog light red.[frame]
