Tracing the vehicle ignition wires

Detach the steering column cover and padded screens to access

the ignition switch and cable harness.
If the vehicle wiring is unknown, the relevant documents on the

vehicle must be consulted or the circuits will have to be traced
using a multimeter or a 12 V or 24 V test light:
1. Switch multimeter to an appropriate DC measuring range.
2. Connect one lead to vehicle earth, for example onto the vehicle
chassis.
3. Test and identify the connections at the back of the ignition switch
with the second test lead:
switch the ignition switch slowly on to trace the voltage at different
key positions.
