How about this, V1 switch? (but the V1 is gone now)

 

How about the original poster just follows the wires and takes pics for us?
No matter what it used to be, I'm sure you can retrofit it to do something nifty...you've certainly been given plenty of suggestions in this thread. I'd turn it into a license plate masker.

 

so did you ever find out what it was?

 

the anticipation is killing me!!!

 

Hey Wait A Minute!! I Have One Too! Wtf??
















J/k

 

I can't belive I folled this thread to the end and have not heard what the switch is for.. Figures.

 

Unfortunately I have injured my back and can't pursue any further. Rest assured I'll get to the bottom of this but for now you will all need to wait in anticipation.

 

that's funny because that's where I have my e-cutout switch.

 

That switch goes directly to the flex capacitor which is located behind the back seat. When you get up to 88mph hit the switch and see what happens.

 

On/Off is a steep curve for volume control.

Options so far:
Amp On/Off: Probably not, they make a remote lead for this job
Exhaust Cutout: Likely, looks like a switch for that kind of thing
Ricer Lights: Also likely. A likely spot for the switch, too.
Fog Lights: I'd think the switch would be on the dash. Running the wire back here is extra work, and not a likely position for fogs.

Whatever it was, it's likely disconnected, so we'll never know.

 

oh well the world will never know until his back gets better
