My brother just gave me some older instruments for my car. There is a SW heat gauge, an oil pressure gauge one SW tach that goest to 6000RPM, There is also a Hotrod tach that goes to 8000 RPM What kind of a sender do I need for the SW Tach. When I was younger I had a Sun tach that had a sender unit. Hope I don't have to find a sender for one of the tachs I have now.
they say a picture is worth a thousand words.... one thousand words... think about that for a minute then come back.
