I have a Pulsar 150cc 2007 model. It has a plastic body. I want to install a remotely triggered siren under my seat (DIY). There is also a small electronic circuit to actuate the siren also to be installed in the same place. Therefore I have to make provisions for the following:

1. Getting a 12v supply (+ve/-ve) wire up there
2. Make a provision for an antenna for the electronic circuit in a water-proof manner.
3. Making the circuit weather proof - protection againt rainly mostly.

Why remote siren?

So I can locate my bike when it is parked in an open ground meant for bike parking.

Why under the seat?

Because I thought it would be safer there...more protected (?) I am not sure about how it will fare against rain.

So if anyone has done something similar can you provide some general tips and safety tips concerning the above three points. - especially the electrical wiring part. I wouldn't want anything to go wrong there...
