box; this has the task of providing the battery + supply,

through internal bridges to the different electric functions of

the vehicle.

A 6 mm

2

cable and a 10 mm

2

cable are connected to it;

through ultrasonic welds they supply certain components and

part of the fuses and relays located on the support on the

lower left part of the dashboard.
In particular, the components and electric functions supplied

by the 6 mm

2

cable are:

- interior lighting, radio-receiver, cigar lighter
- services cut-off relay during starting
- headlamp washer
- 13-pin current socket
- socket for converter

The 10 mm

2

cable supplies:

- ignition switch (base vehicle)
- stalk unit (exterior lights and hazard warning)
- stop lights
- horns
- EDC switching on relay
- instrument cluster with warning lights
- modus diagnostics enable relay
- heated fuel filter
- climate control system
- door locking

Lastly, a 2.5 mm

2

cable can be connected to the control box

which supplies fuse 33 (20A), where applicable, of the

relay/fuse holder support relating to the additional heater

control unit.

Negative network

The battery negative terminal is connected to with a brown

50 mm

2

cable to the earth point m1 to be found on the

left-hand side of the crankcase, next to the starter motor.

From this point, two copper braids are connected to earth

points m2 on the front of the left sidemember and m3, on the

bonnet under the vacuum servobrake. At m3 the wirings

concerning the frame and engine are connected. Near m3,

there is another earth point, called ms3 which, through a 2.5

mm

2

cable performs the signal earth function for the ABS

electronic control unit.
A 6 mm

2

cable also connects the battery cable pin to the

ultrasound weld on which the earth cables of immobilizer

electronic central unit, EDC system function control switch,

EDC electronic central unit and diagnosis connector

converge.

front and right side lighting, windscreen wiper, windscreen

washer, windscreen washer pump and air cleaner clogged

signal switch are connected, is located in the bonnet near the

right front direction indicator.
Earth point m5 to which the components concerning the left

front lighting and the fuel oil heating device are connected,

is located near the left front direction indicator.
Earth points m6 and m7 are respectively located on the right

and left of the cab, near the upper hinges of the doors. To

these are connected the components in the dashboard (stalk

unit, instruments, warning lights, switches), in the doors,

where applicable (power window switches, motors for power

window/door locking, rear-view mirror aiming) and in the

upper part of the cab (roof lamp, front clearance lights).
Near m7 earth point, there is the ms7 signal earth; from here,

a 1.5 mm

2

cable is connected to an ultrasound weld towards

which the signal earth cables of cab/bonnet cable electronic

components like steering column stalk and instrument panel

with warning indicators for diagnosis converge.
Lastly on the floor panel, next to the handbrake lever, there

is an earth point (ms8) specific for the air bag electronic

control unit.
