Can I run the red (fused) power from a 12 volt power outlet to the fuse for the horn (black to ground..obviously) so it turns my GPS power supply on and off with the keyed ignition? Thanks

You could do that, but there is a better option. All generations have fused accessory wires build for this. You will need to buy the accessory relay. What year is your bike?

I wired my GPS directly to the horn (rather than the horn fuse) on my 2007. I'm pretty sure there's no accessory wires available on the gen1 . Works fine, good location to hide wiring and easy to get to. The brown wire to the horn was the +v e but you should probably check yours to be on safe side.

The red wire is attached to the horn terminal using a piggyback connector and if you follow the black wire there's a good ground location close by


I wrapped up the inline fuse in insulating tape, cabled tied everything and located the transformer on the top bracket which gets covered by the left hand fairing

I'll do that! thanks for the pics, easy to follow along, much appreciated!

I ran my grip warmers from the IN side of the 10A horn fuse in the fuse block. It is switched and clean and easy and no electrical tape nightmares. When I say "in", I mean "before the fuse", as my grip wires already have an inline fuse and because it was cleaner that way.

No need to spend the cash for the relay in this case, it's seriously about 2 minutes more work.

"nightmares"?

My mistake. Thanks.

I just 'tapped' into the wires to the DRLs beside the headlamp on my Gen 1s.
