Stu, I never said where to put the fuse.
OK, I'll simplfy my previous post:
Wire from the spare slot in the fuse box to terminal #85 of the relay. From #86 to either the frame, or anything else that you only want powered with the ignition ON.
This will turn the relay state to 'on' whenever the ignition is on.
Then wire the cig socket from NippyNormans to the positive battery feed (via the fuse, as Stu rightly mentionned). Wire the negative wire for the cig socket to the relay terminal #87a. Wire from relay terminal #30 to the frame again.
This means that the cig socket is negatively switched by the ignition. Why is this beneficial? Well, you can then run a positive connection to something via the cig socket, and have the device ground itself, thus completing the circuit without the ignition on. By default, you can't leave a device charging without the ignition on, unless that device grounds itself.
EDIT: Probably the best place on the frame to put negative wires (on a K6 at least), is thr front most bolts on the rear fairing (take the rider seat off, and they're next to the battery). These bolts go down through the fairing into the frame itself.
Why put negatives to the frame & not the battery? Simple, I've had the bike in a couple of garages and been told when I picked it up "We didn't know what all those wires did, so we left them off." GRRRR!!! FKING TWONKS!!! If they only have to disconnect positive terminals, it's half as much work for you to put it back together again.
Comprende?
