Just purchased a Cycle Sound speaker and amp system. I would like to power it off the aux swith and I was told that there is a plug under the seat that can be used for heated clothing or other things. Cant find it. I found the Data plug. Can someone guide me on where I can wire this into? Maybe even a picture emailed to me. Much Thanks. I have a plug with a pigtail to use that someone had but cant find the spot to plug it into.
