-
Never connect fuel injectors with different impedance or of
different models to the same output;
-
The examples shown in chapter 5 can be used to connect
high impedance fuel injectors.
-
When connecting more than one fuel injector per channel,
do it as shown in the diagrams in chapter 5. Do not change the
number of fuel injectors per channel.
4.3 Electrical wiring diagram
5. Peak and Hold wiring examples
The examples below present some connection alternatives, but, when
necessary, it is possible to use only one or two channels, leaving the
other disconnected. 5-cylinder engines must use two Peak and Hold
modules.
5.1 Peak and Hold 2A/0,5A – 4
Bosch 160lb/h injectors
In the example above, Bosch 160lb/h
fuel injectors are used. Fuel injectors
with impedance above 3 ohms (including
high impedance fuel injectors) may be
connected in the same manner.
