I have fitted Sentinel moto alarm to my Tiger usign the alarm connector.
You have to get connector called 'Multilock' including necessary plugs; you might try at
www.rs-components.co.uk
Then you have to check service manual wiring diagram and pay attention where to put proper wires. Also observe original allarm plug - you will understand what has to be connected over alarm relays (immobiliser)
Some experience are required plus some handy tools as it really might disable your bike. But you can still use the original plug, if somethings goes wrong. No damage to ECU shall be possible, as there are only: GND, Vcc, Starter switch, fluel pump, turn signals and LED in the instrument panel.
If you need more info I can send you some photos of my installation as we as RS-components part no#
