INTERPRETATION OF CONNECTORS WIRES FUNCTION INDEX
The information concerning the function of the wires in connectors and couplings included in
Chapter 12, are to be interpreted taking into account the explanations based upon the following
example:
1 = symbol (sign) of the pages containing connectors and couplings
2 = connector destination
3 = vehicle class
4 = manufacturing year
5 = name of the wiring on which the respective connector is placed
6 = wire colour
7 = connector code
8 = component to whom the described connector is to be connected
9 = connector colour
10 = connector symbol
11 = indication of the connector socket
12 = wire sectioning (mm˝)
13 = wire functional code
14 = wire destination
15 = chapter number and connector drawing number
NOTE
Concerning position 6, please note that one X is marked, for one wire and two Xs for two
wires. The colour of the wire is to be symbolised only in case the electric track of the wire
represents one of the fundamental statuses: + permanent (+IC), + after contact (+DC), mass(-)
or controls.
The symbols used for the wire colours are as follows:
A = white
AS= blue
GR= grey
N = black
G = yellow
V = green
M= brown
VI = violet
R = red

PARTICULARITIES REGARDING THE CONNECTORS
DISCONNECTING METHOD
Because this vehicle is equipped with electronics systems controlling and checking different
functions, it is necessary the execution of the electric connection by means of some connectors
provided with securing devices after coupling performing. Due to this reason, in case their
disconnecting is necessary, proceed observing the following observations:
- connectors for: ignition coil (pos.1), canister purging valve (pos.2), AC pressure sensor (pos.3),
atmospheric pressure sensor(pos.4), siren(pos.4), step-by-step engine (pos.5), valve potentiometer
(pos.6), cooling blower (pos.7) are to be disconnected after easy pulling the locking clamp in the
direction shown by the arrow.
- the connectors for: RPM sensor (pos.8), front hood contact (pos.9) are to be disconnected
after easy pulling the locking clamp (A) in the arrow direction, for unlocking.

- the connector of the water temperature sensor (pos.10) shall be disconnected as follows: push
the sensor connector in antipodes points, in the direction of the A and B arrows, achieving in this
way the unlocking of the ( C ) spur, then perform the disconnecting.
- the connectors of oil pressure contact (pos.11) and of the reverse driving contact shall be
disconnected as follows: push in antipodes points in the direction of the (A) and ( B) arrows, achieving
in this way the unlocking of the connector claw, then the connector may be disconnected by pulling
in the ( C) arrow direction.
- the connector of the choke sensor (pos.12) shall be unlocked by pushing the clamp in the (A)
arrow direction, then the connector disconnecting may be achieved.
- the injection computer (pos.13) – the unlocking is performed by acting upon the locking clamp
(A) in the (B) arrow direction, then lift the connector in the (C) arrow direction, achieving in this way
the computer disconnecting. For reconnecting, perform the disconnecting operations in the reverse
order.
