    I have a Softail Heritage 2007. I noticed what looks like the end of a wire with a bar connector, kinda like what a trailor light plugs into when you hook it up to your vehicle. It is almost directly below the oil cap, very close to the shock at the bottom of the frame. What is this and can any goodies plug into it?

    Sounds like the plug-in for a battery tender. Trace it back to see if it connects to the battery and to nothing else.

    Local dealer automatically installs one on every bike they sell. Might be the case here.

    Good luck.

    Got a digital camera? Take a picture and get a definitive answer.

    I'm banking on the battery tender pigtail too...can also look at your battery posts to see if the other end connects to them. If true, might want to ask previous owner/dealer if they have the charging unit that plugs into the pigtail. If not, Deltran sells the one marketed by HD. Here's their site:

    Discovery is a beautiful thing, but it goes 2 ways, the observer and the scribe to document it...there are a lot of plugs "under the hood (seat & covers), so clarity is also a good thing and a picture is worth a thousand words. A couple more plugs are the Diagnostic plug and the more difficult to find Auxiliary Accessory plug as far as "open" unlabeled ones.

    Just took another look at my '07 in the morning light.

    If the plug is about 3/4" wide, black, and has two wires, would be the battery tender plug.

    If about 1 1/5" wide, black with a cover, and has four wires, it would be for the tech's use in diagnostics and emissions inspection. This is probably tucked up higher on the bike and closer to the ECM.

    Could even be a plug-in for electric vests, etc., the prior owner added.
