Ok, yesterday I pulled my battery to install the ring terminal harness from my new Battery Tender. In the compartment where the battery sits I found a yellow connector just sitting there. It's a three wire female end connector. I looked and couldn't find the other wired end. I did find a housing that it fit into and clicked securly to but it is hollow inside, no connections. Bike obviously runs fine. My question, what is this connector for? I did a quick search in my HD repair manual and could not find it. I don't have the manual with me right now so I can't do a more thorough search. Just curious what that connector is used for. Thanks.

 

probably accessory power. i have one under my seat- orange. it only gets power when bike is on.

 

It sounds like the connection for a security system siren. At least that's where I connected my siren on an 09 XL1200C.

 

Plug for Scanalyzer? Just a guess....

 

if it is triangle shaped it goes to the siren if you have an alarm installed. Other then that it is not used.

 

The siren connector on mine is a 3 wire flat connector that has a plastic cap that goes on the plug. It is just in front of the battery.
