Here's what I have so far,
1. Red wire with Fuse from Alarm needs to connect onto red +12V wire from battery.
2. Orange wire from Alarm needs to connect to Orange wire from Ignition switch.
3. Pink wire from Alarm connects to Or/Yell from Ignition. (not clear from Busa manual - double check this)
4. Cut pink to Grey connection on Alarm.
5. Blue on Alarm goes to Yell/Green from Starter Button
6. White on Alarm goes to +12V red from Battery.
7. Both Yellow wires on the Alarm - one goes to left turn signal, one goes right. Both blue wires.
8. Looks like the siren and override switch have their own connectors so should stay as they are on the diagram.
This was taken from a 99-00 wiring manual so check to make sure you have the correct year. Anyone else want to check this to make sure I haven't made a horses ass of it feel welcome.
