Location of horn with relative connection.

Pin numbering for wiring harness side dashboard connector.
Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
Low beam lights not working

Lcd.
Neutral light n (green). Illuminates when the gearbox is in neutral.
High beam light (blue).
It turns on to indicate that the high beam lights are on.
Engine oil pressure light
(red).
Illuminates when engine oil pressure is too low. It must turn
on at key-on, but ...
Disassembly of the gearbox shafts
Place the shaft in a vice in such a way as to facilitate the disassembly
operations.
Important
Take care not to invert the positions of the shims on reassembly:
this would potentially lead to jamming when using the gear selector control,
making it necessary to reopen the engine
crankcase.
