Apart from the electrical branches taken

off for the obligatory signalling devices,

the vehicle’s electrical system can only be

connected to the supply cable for an elec-

tric brake and to the cable for internal

light, though not above 15W, in the trailer.

The electric brake must be directly sup-

plied by the battery through a cable with

a cross-section of over 2.5 mm

INSTALLING TOW HOOK

(fig. 3)

The chart shows the attachment points

for fixing the tow hook to the body.

These points must not be changed irre-

spective of the shape and size of the

hook. For mechanical connection the fol-

lowing must be used:

– “ISO 50” 2nd category ball hook

(CUNA Table NC 138-40)

– 2nd category ball eyelet model “CU-

NA 502” (CUNA Table NC 438-40)

The tow hook structure must be fas-

tened in the points shown by the symbol

Ø

with a total of 12 M10 screws.

The inner plate (1) should be at least 4

mm thick.

The side plates (2) should be at least 5

mm thick.

The fastening points (3) must be fitted

with a spacer with a 25 mm diameter

and 6 mm thickness.

IMPORTANT It is compulsory to fas-

ten a label of suitable size and material

(clearly visible) at the height of the hook

ball with the wording:

MAX. LOAD ON BALL 60 kg.

ELECTRICAL CONNECTIONS

The attachment for the trailer wiring

connections are to be applied to the tow

hook support in the most suitable posi-

tion.

For the electrical connections a 13 pole,

12V connection must be used.

For vehicle-trailer electrical connections

contact Authorized Alfa Romeo Services.

Do not connect any

trailer services (fan,

fridge, etc.) to the vehi-

cle’s electrical system.

After assembly, the fas-

tening screw holes

should be sealed to prevent the in-

filtration of exhaust gas.
