WIRING DIAGRAMS
IMPORTANT NOTE: Not all of the components listed here
are fitted to all models.
IMPORTANT NOTES:
3. We have sometimes shown the wiring diagram for a
'highest' spec, model, in the knowledge that 'lower'
spec, models are usually similar with the deletion of
certain components.
1. There are several hundred FIAT wiring diagrams for
the whole TIPO range. This is a representative selection,
covering the majority of applications. However, in the
event that your car's details are not covered here,
consult your nearest FIAT dealer.
2 All of the following are Tipo wiring diagrams. Tempra
saloons and estates are essentially similar.
4. 'EEC Stage 2 Engines' In late 1994, Tipo 1.4 and 2 -
Litre and Tempra 1.6 MPI vehicles were modified to suit
new emission regulations. These changes were NOT only
engine-related. Vehicles covered by this manual are Tipo
1.4 (with engine code no. 836A4.000) and Tempra 1.6
(with engine code 159B9.000). See Page 27 for location
of codes.
