I've done the same, except that I mounted the little 
momentary-contact switch below the dash above the clutch pedal--on 
the plastic air duct that runs just above the pedals. It's so 
stealthy that I usually need  to grope for a few seconds to find it. 
It's reachable from a seated position. It's perhaps the most fruitful 
20 or 30 minutes you can spend on your car, IMO.

Oh, that 20-30 minutes doesn't count the replacement of the 
check-engine bulb. :-)
