sunpro tachometer

[manyolkars]

My son donated a Sunpro tach he was using in an 8 cylinder car.  I'd like to use it on my 4 cyl Model A.  Does anyone know where to set the dipswitches? Google didnt help.  I looked it over and dont see any ID other than 10,000 rpm Sunpro about 3.5 inches, white face. It has 2 reset knobs on the front.  Thanks

The info on the Sunpro website for 3.5 inch whiteface tachs is wrong.

The correct info for 3.5 tachs is listed under the 5 inch  information.

Of course! I shudda known THAT!
