[s-cars] Dash toggle switch

[P. Dooley]

S-Heads,

I have the 034 RS2 ECU upgrade in my 95 S6.  This software has a normal 
setting and a hyper setting (normal = 87-89 octane and peaks at 20PSI 
and hyper is 91-93 and 27 PSI).  Currently I have a plain silver toggle 
switch to go between the two settings (like I ever drive it "normal" but 
when the better half drives the car or heaven forbid a wrench),   I'd 
like to blend this toggle switch into the dash and use one of the blank 
switch slots next to the front seat heater switch.  So, does anyone know 
which factory switch could be pulled out of a donor car that would mimic 
a toggle switch? 

I'm thinking maybe the two-way radio switch - 4A0-035-775.  Think this 
would work?  Anyone have one they're not using?
Probably either the front or rear fog light switches would work - 
4A0-941-535 or 4A0-941-563-C.  Having the amber or red illuminated 
signal would be nice.
Switch for roll blind would probably be a momentary switch, not a toggle 
switch - 4A0-959-903.

TIA,

Paul Dooley
