How does it affect the security on the scooter? When you shut down and turn the bike off, the front and rear lights flash twice. Have you tried setting off the alarm?
The alarm works with the turn signal output, not the break lights. This modification has no adverse effect on any signaling functionality of the bike. Hazards, turn signals, etc. work the same when applying the breaks or not. You would never know that it wasn't designed to operate this way.
FYI, the SERG has three outputs to the tail lights (running lights, turn signals and break). These are independent circuits and are designed to work together. You only splice into the break light wiring to get the Back Off device to work. The turn signals override break light input and flash as they did previously. It's cool stuff.
It would be very helpful if you could post a few pics and idiot safe instructions for us novices.
Unfortunately I did this install in my hangar at the airport and didn't have my camera with me like I normally do. I will shoot a few pics of the final product and post them as soon as I can get the time.
