Does anyone know if there is a wire or plug connected to this switch? I am thinking of adding an xm but I need a power source. I would like to power off the ACC switch.
Thanks

 

Under your seat - in front of the battery there is a opening - it should be in there with a cover

 

It's probably dark grey or black. 4 wires into it. Check your manual wiring diagram for the wire thru the switch. Some years use orange/red. You can get the post to crimp on the wireto your device, the rubber shield it pushes thru and hold it into the connector, and the male end to mate to the connector from your dealer. There may be an existingcover on the connector that will need to be removed and tossed so the male end with the new wire will clip in. It will likely run thru the 15 amp "P/A" fuse in the fuse block.
Disconnect the battery (neg. 1st) before you start. The battery may need to be removed to get to the connector.

 

Air and heated seats plug into the switch, under the seat. There is also a part in the Harley catalog for a splitter, making two plug-in's out ofone.

When I got my Air Zeppelin, I had a heckuva time plugging it in. I cut all the wire ties in the immediate area, and freed up a lot of slack in the wire harness around that plug in, and then retied.
