Under the seat of my new 04 fatboy..never seen anything like this. About the size of a box of matches with a SE sticker on it(radio shack project box, from the looks of it)
Havent opened it nor traced out the wiring under the tank as I dont have the bike back yet. Not a fueler, looks to small to be an ignition module. Besides its an FI bike and is controlled by the computer..

Thanks

 

Auxiliary Running Light / Brake Light / Turn Signal Conversion Kit??????? maybe?

 

It's the control box for the air bag and ejection seat. You can tell by the tan wire.

 

Cut the blue wire...

 

sert maybe?

 

That is what’s called a thingamabob; you got the high dollar one with wires coming out.

Sorry this snow is making me crazy.

 

It's either the controller for the 8-track deck, or the fuse for the Mr Fusion Propulsion system

 

it's the eminent rain warning device. when it sounds, head back to the house!

 

I believe that is a se race fueler. a tuning device, and not a very good one

 

Whatever it is, you should secure it with velcro or 3M tape, so it doesn't bounce around and get damaged.
