Installing a SPY 5000 two-way motorcycle alarm into a Honda 1998 CB250 Nighthawk

This Instructable describes the installation of a SPY5000 two way motorcycle alarm with a Honda 1998 CB250 Nighthawk motorcycle.

This Alarm is rather typical of after-market motorcycle/ scooter alarms available all over the world. My installation was not standard, and was more complicated than I expected, so I am sharing my experiences and knowledge  to possibly assist anyone else who finds themselves in a similar situation. I have found previous guides lacking some of the finer detail which may be required, so I have included as much information as possible to hopefully aid the reader.
