OK. I picked up this nice Stewart Warner Greenline tach at a swap about a year ago for my '56 hot rod. It's the later type with the internal sender. I have no instructions and can't find any on line, so before I guess and maybe blow the thing up (it's supposed to be in working order!), does anyone here know for sure how to wire this. I know one post should go to the coil and the other to ground, but I'm iffy about which is which to tell you the truth . . .
