I'm looking for a tach kit that allows me to run a series of LED (hidden) in my 67 cluster but really have not found what I'm looking for. Anyone done anything like this? Here is an ebay auction with a digital meter to give you an idea. http://cgi.ebay.com/ebaymotors/_W0Q...emZ190521838649QQsspagenameZSTRKQ3aMEWAXQ3aIT I only need a circuit board to run a series of LED's that can be dimmed at night.
