I aquired an instrument cluster from a u12 pintara trx wich has tacho and oil pressure gauge. CA20 corsair's did not come out with tacho or oil pressure gauge (only switch) that i know of, and there seems to be no wiring for the Tacho. Has anyone done this conversion, i have installed already thinking that the wiring would already be there. How do i make this tacho work? Do i have to run new wires to the distributer, is it different because it is a twin spark motor? Ur help would be appreciated.
