I was just checking to see if y'all were paying attention........

 

From the 2015 Road King Online Owner's Manual


See Accessory Connector (under left side cover). The accessory switch controls power to the accessory connector under the left side cover. See a Harley-Davidson dealer or www.harley-davidson.com for electrical accessories that may be purchased and installed on the motorcycle.


FLHR/FLHRC: See Nacelle Switches: FLHR/FLHRC. The accessory switch is on the right side of the nacelle.

Other models: See Fairing Cap Switches (typical). A panel for accessory switches is next to the ignition switch in the fairing cap. Switches can be added for installed accessories. The maximum load per switch is 2 amps.

1. Auxiliary/fog lamp switch
2. Accessory switch

Nacelle Switches: FLHR/FLHRC




I still don't know what the plug/connector is for.

 

So, I went out and removed the side panel and found 2 plugs with 2 different connectors.


I plugged my auxiliary power port http://www.harley-davidson.com/store...05-69200855--1 into the connector that fit, and my phone charger worked, but the switch on the nacelle had no effect.......

 

Thanks for posting that.It seems Moco decided to change switch locations after all these years.Maybe to convince potential buyers that the Road King has many new features.LoL

 

Your switch has no affect because the plug is multi-wired. On pre-14s the 4 wires were
Ground
On with ignition
On with ACC switch
On with brake.

The accessories have 2 wire, ground and one of the other 3. Depending on how the accessory is wired will determine when it has power. The 12 volt power port from HD uses the on with ignition.

I say "pre-14" because I've heard there is a slight difference but not 100% sure at the moment but similar enough.
