For navigation and for heat. Like I do with all bikes I wanted to be able to power a GPS, a vest and heated grips. There's nothing earth shatteringly complicated about doing any of these things but I haven't seen much on the subject specifically relating to the 690's. So to start with I ordered some stuff from Powerlet and Symtec heated grips from CalSportTouring. I went with Symtec for the heaters for two reasons, one, the choice of switches and two, they have two circuits for high and low instead of some versions that use resistors to change from high to low (waste of power and pain to wire cleanly). I went with the metal toggle because I've preferred it in the past. In this application, with this location I might have opted for the little plastic one. Once I get the little rubber boot I'll be happier with this one. I had gone to the geek store (Radio Shack) and picked up a relay so I could avoid the inevitable dead battery from hot grips while parked scenario. Well once I got into the project I realized the nice engineers at KTM had given me ACC1 and ACC2 leads to work with under the headlight. One is always hot the other is switched with the ignition. I used the switched one and didn't bother using the relay. The ACC1&2 are both rated at 10A so my 3A grip heaters shouldn't tax them at all. Here's a picture. You can see the two red wires joined and connected to the brown wire in the center. They are the ground wires from the grips going to the ground from ACC2. The BLK/RED wire to the right of them is the hot (switched) going to the grip heater switch. I routed the wires along the path of the clutch hose.
