overdrive questions.

["Scott J. Hershman" <SHershman@compuserve.com>]

My "new" 6 has overdrive and my old 6 did not.  The PO has it wired to a
rocker switch below the gearshift.  

Does anyone have a picture of what the overdrive switch and escutcheon are
supposed to look like?  
Does the stock set up have an indicator light to show the OD is engaged?
At what speeds/RPMs do you typically engage and disengage the OD?
When do you use OD in 3rd gear as opposed to 4th gear?

Thanks,
Scott
