uns from under the dashboard forward through the front bulkhead of the<br />

monocoque and through the tunnel to the back of the car. Both the front and<br />

rear auxiliary looms unplug to enable the front and rear panels to be removed<br />

complete with their own lamp wiring looms. By using its own wiring loom at<br />

the back and making connections under the dashboard the completed car is<br />

very neatly wired.<br />

The standard Rover Metro steering column switchgear is retained within the<br />

<strong>Libra</strong>. No wires run through the passenger compartment.<br />

Wiring loom and electrical component assembly<br />

Consult drawing No 27. Lay your K Series Rover Metro wiring loom out on<br />

the floor and identify the basic layout. The main body of the layout runs<br />

across the car inside the dashboard. This part of the layout has the fuse box<br />

attached to it and the plugs for the steering column switches and the<br />

dashboard loom. The fuse box is on driver’s side of the car. Running forward<br />

from this loom on either side of the car are two legs which, on the standard<br />

car run forward to the lights on either side of the car. They can be identified<br />

by a large grommet on either leg. This grommet is approximately Ø60mm.<br />

The grommet is used where the wiring loom goes through the front bulkhead<br />

of the car on the Rover Metro and is used in exactly the same manner on the<br />

<strong>Libra</strong>.<br />

On the passenger side of the car just before the wiring loom goes through the<br />

large grommet there is also a leg of the wiring loom which on the standard<br />

Rover Metro runs down the passenger side of the car to the rear of the car.<br />

This leg of the wiring loom has approximately 40 wires in it. This rear leg<br />

leaves the wiring loom that goes across the dashboard at a junction and then<br />

approximately 100mm from the junction spurs leave the wiring loom with black<br />

plugs on them which on the standard Rover Metro are used for the electric<br />

windows and central locking. A further 120mm along there is a purple and<br />

white lead approximately 200mm long that has a single spade connection.<br />

After this lead allow approximately 100mm and cut the wiring loom at this<br />

point all the way through the 40 wires. The rear end of the wiring loom is not<br />

used at all on the <strong>Libra</strong>.<br />

As on the standard K Series Metro the legs of the front wiring looms run<br />

through the bulkhead of the <strong>Libra</strong> through the standard grommets and down<br />

towards the head lights on either side. A small auxiliary wiring loom is used<br />

on the <strong>Libra</strong> to wire the head lights etc and then comes through a grommet on<br />

the passenger side of the car in the radiator ducting to a plug to enable the<br />

bonnet to be removed without having to undo all the head light wiring etc. The<br />

main auxiliary loom on the <strong>Libra</strong> connects to the standard wiring loom on the<br />

passenger side of the dashboard through the standard grommet on the<br />

passenger side and then connects to the standard wiring loom at several<br />

points before going through the tunnel to the rear of the car. At the rear of the<br />

car the <strong>Libra</strong> wiring loom connects to all the auxiliary equipment and then<br />

through to the back passenger side of the car where it is plugged into another<br />

auxiliary wiring loom which runs to the lights at the rear of the car to enable<br />
