1. Signal to be supplied through connection on the trailer,
to permit trailer lights and parking sensor diagnostics (if
present)
2. Pin 12 could be absent as it may have been replaced
by a switch integrated in the socket; in this case it is not
necessary to perform any connection on the trailer
13 Ground 0000 –
▶ The electrical connection of a trailer entails a considerable increase in the length of the cables
and results in a larger voltage drop on the line. Therefore the use of cables with the biggest pos-
sible cross-section is recommended, which are compatible with the system layout and with the
13-pin socket; on this it is then necessary to divide the ground return by using all three pins 3, 11
and 13.
Side Marker Lamp installation
The installation of the lateral lights must be performed on the additional structures (containers, vans, etc.), while the electric power
supply must be obtained by the specific ST38 connector on the chassis (see Figure 45).
In order to keep the electrical characteristics of the contacts of the female socket unchanged, the hood supplied by IVECO must be
left attached.
▶ It is not possible to draw current from side marker lights.
