Help with Tach
Anyone help with hooking up a Tach ?? I have a 84 Monte & I got a tach out of a SS I want to put in. Mine has 2 metal pins on the back plastic and the SS has 4 metal pins.(see pics) 2 of the pins are marked with a - & +. what are the other two pins for ? Since mine has only 2, How can I wire it up to work ?
