Follow these additional instruc-
tions for European models only.

to the red wire of the PCIII
(Fig. J).
2Locate the black wire with a
white tracer on the grey connec-
tor side of the ECU (Fig. K).

completely closed (Fig. K). It is
recommended to use dielectric

Power for the Power
Commander is supplied from the
tail light circuit. On European
specification bikes it is possible
to switch the light circuit off (via
the handlebar switch). This will
shut off the power to the Power
Commander causing the bike to
stall.
It is necessary to use the power
lead adapter and wire tap on
European bikes to maintain con-
stant power to the Power
Commander. It is not necessary
to use these parts on a U.S spec-
ification bike as there is no per-
formance advantage.
