Default What does this button do ?

While doing a tune-up on the engine yesterday, I found this button attached to the lower drivers dash. It says "Rally" on it and it is a momentary single pole switch. I tried to follow the wire and it disappears way up behind the dash. See attached pics.

Has anyone seen this before? I am afraid to push it because I have no idea what it is. Alarm? Engine disable? I'm not gonna chance it at this point. Looks to be aftermarket, but might be RT OEM.

If it is momentary contact, it is likely a "boost" function for starting your engine with the help of the chassis battery. If so (and if it is working), you will hear a click when you press it as the isolation relay closes

If it is not momentary, there might be aftermarket fog lights or some such.

It powers up the Turbo Encabulator.

No, really, I have no idea, but the fog light scenario seems logical.
