SPORT IMPORT APPLICATIONS
Honda and Acura
For early applications, connect the green wire to the blue
wire coming from the distributor. On late model
applications, connect the green wire to the yellow wire with
the green stripe coming from the Ignition Control Module
(ICM). In some cases there may be a diagnostic plug found
in the corner of the engine bay (driver's side) wherein you
can splice the green wire into the blue wire. If this method
does not work for the late model applications you may be
able to connect the green wire to a tachometer test
connector wire (typically a connector with a blue wire)
found behind the battery in front of the air cleaner opening
on the passenger side fenderwell
