Important installation tips when
installing the Power Commander
When installing a Power Commander
on a Harley-Davidson it is critical that
the rubber boot is removed from the
factory connector and installed on the
Power Commander connector. It is
equally critical that the boot is then
installed correctly on the ECM after
the connector is in place.
The boot must fit over both bosses
and down around the sides of the
ECM to properly keep out water.
The ECM has aluminum
bosses that stick up on
either side of it's connector.
