EXTRACTME 12V Fuse Block, Universal 20A Motorcycle Fuse Relay Box Kit with LED Warning Indicator, Motorcycle Accessory Power Supply Unit 4 Circuits, Fuse Box Battery for 12 Volt Automotive Vehicles

I have the exact set up you have, 2009 with the Klr dash and quad lock with vibe dampener. I have the usb version so I opted for the smart switch that goes directly to the battery, pretty nifty. I also got a 12V 20amp relay fuse block and found keyed power on the aft end, left side of the bike. Get a voltmeter and start poking around for 12v power in one of the two plugs. One plug is going to be for the turn signal, the other the brake light. Use the brake light, don’t use the turn signal one for obvious reasons lol.
