Hi Hugo,
Pleased that all is going well. I have a motolita and boss and the inciators do cancel (both directions) but could be better. I suspect that it will be a simple plastic cam on the steering shaft that rubs the indicator stalk and turns it off. I had the same problem on my +8 and by adjust its position it sorted it, just need to take cowl off and possible steering wheel to get to it.
The alarm sensors are not on mine, possibly a previous owner had it fitted. I'd be careful about just cutting the wires to remove them in case it's still active and this disable the car. If you can disconnect them and then remove the sensors, hide them behind the dash and then reconnect that may be best. But it might be best to get a car electrician to take a look.
