Default What is this plug

Hi everyone, just got my first Harley and was changing the seat. I noticed a plug not connected to anything. Can someone tell me what its for and is it suppose to be connected to something. Also its a 2003 fatboy. Thanks

That appears to be the diagnostic port to hook your bike up to a Centurion Diagnostic tool or to HD's Digital Tech for bike diagnostics...

Or is it the accessory connector plug. On my 04 FLHTCUI, it is the accessory plug. My is a square, 4 prong plug

Gray color makes it the diagnostic plug.

Diagnostic plug. The bike is a 2003 fat Boy. I don't believe that they have accessory connectors on them.

While on this subject, anyone know what these things are under my 09 FLHTCU seat? The long gray one under my fingers simply has a thicker red single wire to it; I know the narrow black one is the antenna for the fob; no idea what the one is that has the red on it. The manual calls it a "purge solenoid", whatever that is. Just looks like a two wire connector with a dust cap to me. Anyone know?
