9.1.10 Main wiring earth
Next wires exiting the loom will be the thick multi black earth eyelet, which should be bolted to the left hand
bolt in the roll hoop that holds the wiper “Z” bracket, clean this area to make sure of a good earth connection.
This should already be connected from section 3 above to help position the wiring loom.
9.1.11 Electrical instruments and Automatic gearbox illumination
Along with the earth eyelet are six wires provided for electric gauges and Automatic gearbox illumination.
Some gauges may have + marked on the gauge others can be connected either way around.

9.1.12 Low charge warning
The remaining wires should follow the wiper drive track and turn back across the dashboard from left to
right, all the instruments and switches can be wired and fitted at the same time or you can fit all instruments
and switches and wire from behind. The first two cables are for low charge warning lamp these will need
female spades crimped or soldered on.

9.1.13 Heater fan switch
The next two are for the heater fan switch. The heater fan switch has screw terminals, as with all this type of
screw terminal connection the wires need baring back before inserting behind screw (the connection will be
stronger and longer lasting if you tin the wire ends with solder before inserting in switch).

Next
fit the water temperature gauge, if using electric gauge extend wires to reach wires in section 12
above, if using Suffolk Sportscars supplied mechanical gauge the capillary tube needs to be fed through the
dashboard
