•
Check the vehicle speed pulse signal, parking brake signal and reverse signal carefully before making
the connections. If the cables are incorrectly connected, accidents or problems with correct operation
may result.
•
The label on the vehicle speed pulse signal cable contains a protection circuit, so do not cut the cable
or remove the protective circuit, otherwise problems with operation may result.
•
Bind the cables together with tape so that they do not cause an obstruction while driving. If they
become wound around parts such as the steering wheel, shifting lever or brake pedal, accidents may
result.
The locations where the vehicle speed pulse signal cable, parking brake signal cable and reverse cable
come out vary depending on the vehicle model and grade. Ask the place of purchase for the vehicle or
your nearest dealer for details.
