How hard is it to?

 Hey,

    I need to run a power wire for a GPS unit (Zuma 550)I was wondering how
hard it would be run it myself and hide the wire, etc.
Ideally, I want the power to only be supplied while the key is in the on
position.

    I have a '07 Yamaha V Star 1100 Silverado.

    If you have any thoughts on how I can do this, etc. Let me know. Of
should I look at "local" shops?

Thanks,

TC
