Hi folks,

I am trying to hook up my TomTom gps and need a source of power that is only on when my scoot is running. It is a 2016 500 sport.

Can anyone recommend where I can tap into switched power without removing all of the plastic on the front of the bike? Maybe in the battery compartment? Near the fuses by the floorboards?

Thanks!

You could pickup a live from the headlight circuit and use it to trigger a relay. Don't wire it direct to the circuit, or you could blow the fuse - but a relay shouldn't hurt it.

Thanks, but where would I get to the headlight circuit without taking the whole front end apart?

You should be able to reach up behind the headlights without removing plastic, or you could take a feed from the tail lights.

Perfect! I know how to get to the tailight wiring!

Thanks so much for your help.

Depending on where you are going to mount the GPS unit, you might still need to remove a couple of plastic panels at the front anyway.

I got the mounting bracket installed and wired back to the battery compartment, so now it's just a matter of finding that tail light wire to tap into.

I now have mine powered all the time, unless I disconnect it (remove inline fuse). I used to have it ignition switched, but that was often a PITA. It was surprising how many times I wanted the GPS to work while the bike was switched off.

Thanks Jim, I tried that first and it destroyed my bikes battery over a weekend even though the GPS wasn't turned on.

I agree though, I often use it when the bike is not turned on.

Ah - but I always removed the GPS from its cradle when not using it. The cradle has (at least for my Garmin) a pretty low standby draw - about 10mA. So not a problem I encountered.

Found the tail light positive wire and hooked it to a relay and used the relay to supply power to the gps. So far, it is working fine.

Thanks again for all of the help!
