Default Road King Accessory Switch

Can someone tell me where the accessory switch on the 08 Road King (Classic) wires are located. I want to use this to power some 12 volt stuff. Is it under the tank?? Any help appreciated.

Thanks I found the 4 pin one. Do you know how the ground is routed or is it a frame ground?

What's the difference between a dirty and clean ground

and

There is a gray connector with a single red wire in it, any idea what that's for.

thanks for the help.

PS: I do have a service manual but I'm still an idiot.

It's not in the 08 manual that I could find, this is from the 2014 manual:

One of the 4 pins in the accessory plug is a ground. The others are on with ignition, on with ignition and accessory switche and a brake light wire.
The single plug with the red wire is a B+ line, meaning 12v constant. It's only fused through the main 40A fuse. Great for things that use a heavy draw or that you want to be always powered like a power point.
