To finish this area of the dashboard you will need to connect up the mechanical parts of the gauges. Start by drilling a
hole in the bulkhead behind the speedometer. This hole could take the speedometer cable (104), water temperature
capillary tube and oil pressure pipe (both come with instruments) into the engine bay or you could use separate holes
if required.
The speedometer cable needs to exit the dashboard behind the gauge then curve down and back beside the starter
motor and under the clutch slave cylinder and into the gearbox via a 90degrees adapter. The water temperature
capillary tube needs to exit the dash and follow along the top of the inlet manifold and connect to the radiator header
tank. This pipe can be “P” clipped along the manifold studs where necessary. The oil pressure pipe needs to exit the
dash and head down to the engine oil filter housing or one of the blanks in the engine oil ways. Take care not to kink
or to tightly curve any of the above and gently coil any excess pipes behind the dashboard.
Next move to the centre of the main dashboard and connect the headlamp switches (122), on mounting panel (113)
and map light (117).
P Brown Live into side/marker lamps
Red Live out of side/marker lamps, this wire needs linking to the input of the panel and
headlamp switches
Red/White Output of panel lamp switch
Blue Output of headlamp switch
Purple/White Map lamp live in, connect other side to earth
Next, find a suitable position to mount the horns (115) under the bonnet. They usually mount hanging down from the
angled top hat section on the bulkhead approx 11 inches from the centre. Drill suitable holes and insert Nutserts.
Behind both horn positions drill a hole in the bulkhead for the cable to exit from the dashboard.
Q This pair of wires exits the dashboard behind the left horn.
Purple/Black Live into horn, connect a separate wire on the earth terminal and send this back into
the dashboard and connect to earth
Yellow Live out to overdrive via inhibit switch, run this wire down the bulkhead and connect
to inhibit switch and overdrive solenoid (secure with “P” clips where necessary)
R Blue Live input to headlamp dim/dip switch
Blue/Orange Dip beam out
Blue/Black Main beam out
The headlamp dipswitch (114) can be mounted in various locations i.e. on a bracket on the gearbox tunnel or with the
other switches to the right of the driver.
S This pair of wires exits the dashboard behind the right horn.
Purple/Black Live into horn, connect a separate wire on the earth terminal and send this back into
the dashboard and connect to earth.
Purple/White Live into under bonnet lamp 116. This needs mounting on its angled plinth so its
points towards the carburettors, drill two mounting holes for this above the right hand
top hat in line with the carburettors, connect a separate wire on the earth terminal and
send this back into the dashboard and connect to earth. This can then be secured using
Nutserts or similar.
T These wires connect to the switches (123/4/5) and are to be fitted in the driver’s side alloy panel. Drill the
required number of holes in the side panel in a horizontal line equally spaced apart approx two inches from the bottom
of the main dashboard. Keep the most used switches closest to the driver for ease of use. Our suggested order would
be: Indicator; Overdrive; Map/Bonnet; Spot lamp; leaving fuel pump furthest away to the right so as to be less likely
to switch off by mistake when driving.
Green x2 Indicator switch ignition live in
Green/Red x2 Indicator switch left flashers out, terminal G (if having toggle switch hanging down)
Green/White x2 Indicator switch right flashers out, terminal D
