Just purchased 2015 Ultra Limited. I have the service manual, and a parts manual but still struggling on which connector I need. There are two accessory connectors under the left side cover, and I am using the one on top for a connection to the Road Zeppelin seat I just purchased (no fat *** jokes pls). The other connector below it will not fit the accessory harness I just bought... this one:

I'm trying to connect this bottom plug into a set of Mighty Mites cooling fans... see photo. I think the connectors on the bike are called A and B, but I did not realize they were different pin sets... anyone know what I need?

Thanks, Jethro

 

one plug is for diagnostics and tuners, the other is for accessories.

 

The plug with the six pins is for the tuners I believe

 

Thank you gents. I will wire the fans separately into the accessory harness.

 

On my 16 Road Glide Ultra, under the left side-plate cover I used the accessory connector to run power to something I was adding. I bought a wiring 'kit' from the dealer for 20 bucks that plugged into the 'accessory connector' and it gave me a small four pin connector where I could plug something into and also split off 3 individual wires for splicing. Even the four pin connector used just these same 3 wires. One wire is a ground the other two were hots. One of the hot wires were live all the time, the other was controlled by the ignition switch. So, whether you used a 4 pin connector or used the individual wires (like I did), you could configure it to power something that turned off and on with the ignition switch OR if what you were installing needed power all the time and/or had its own power switch it could be configured for that too. I think the 'harness kit' I got from the dealer is what they use to plug into that accessory connector for installing heated seats, if I remember right. just in case that helps at all. The connector is #7 in the pic below.
