Now there is a cable for H-Version (03-164). There are 5 ferried cables that make it easy to install.
Red: The H-regulator must have a separate power supply so removing the car fuse box is a good voltage source of the H regulator (03-164). This is to prevent e.g. voltage spikes from the ignition coil.
Black: Good chassis earth.
Blue: Connects to the relay.
Yellow: Rev signal, e.g. from generator or crankshaft position sensor.
Brown: Speed signal, e.g. from the car's existing speed signal or from inductive sensors.
Cable length: 3 meters.
