Well, sort of. In this picture you'll see the power strip and the fused accessory leads coming off it it. What you don't see is the relay, which I put in the battery box. All you do is run an ignition controlled power lead (say off of the accessory plug in the front of the quad or tap into the keyswitch lead), run that back and tie it into a basic auto relay (found at any auto part store for $5-7). Run power from your battery to the relay, as well as a ground to the relay. Then, you take the outputs from the relay and run them to the power strip (which is shown in the picture). From there, you run your accessory lines off of that and fuse them accordingly.
The picture isn't the sexiest you'll find (I've since put plastic conduit over the gang of wires running along the frame. The yellow one is the switched power lead. The green wire on the upper left corner isn't related to that...that's for my portable tach when I'm tuning things on the bike. I just ran it there to keep it handy. The two relays are for my winches. It's awfully "busy" under the seat, but it keeps all that crap high and dry (for the most part). I did that on my V2 and nothing ever shorted out. Come spring, I'll be doping up that terminal strip with silicon to protect it better. The relay usually needs to be changed every year or so due to the bouncing and such it takes (which it's really not designed for), but it works. It's worthwhile to keep one as a spare if you rely on this system heavily.
