2008 Ultra. The prewired accesory swith on the dash runs down to a plug that is in front of the battery or between the battery and the rear cylinder area. I found the plug and that part I am all good with. The question is, there are three wires going to this plug. What color is what? Thank you in advance for any feedback.

 

You mean three wires in addition to the switch? Two orange/red and a black plus the switch being red/yellow? If so then then the two orange/red go to the customer accessory fuse and the black one goes to ground.

 

Kind of, just the under the seat plug that has a factory installed rubber plug in it. That plug has 3 wires running into it. Those three are the question. Thanks again.
