I have a 2017 Ultra Classic Low and I want to put on a Mustang Heated seat. Problem the connectors on the seat and the bike are different. The other problem is exactly where is the correct auxiliary harness?
One post tells me it is under the right side cover the next says its under the left side and yet another says its under the seat in front of the battery? I understand that there is a electrical connector update kit but all the post I have read say that the Harley instructions suck.

Law Abiding Biker has a YouTube video showing a heated seat install on a 2014 Rushmore Street Gide, seams simple but where the hell do the extra 3 wires on the electrical update kit go?

Has anyone else had this experience and did you do it yourself or take it to the dealer?

You need Harley part no. 69201599; this is an adapter kit that marries the, "Old style plug" to the new 2017 style. You should find the new style Acc. plug behind the right side panel, that's where I located it on my 2017 ultra limited. You only need to route the new wiring from the kit and plug into the new style plug from the right side of the bike and the old style to the Mustang seat. No need to wire to the battery unless you plan on running more accessory items off this same adapter.
