The Tach/Meter Match is installed with four external wires connected to an internal terminal strip (see Instruction Manual links for details). Wire size can range from #14 to #22. If you don't have wiring supplies readily available, the model WK-01 wiring kit consists of four 36"-long wires, one each of red, black, orange and white. Also included are four butt-connectors and two ring terminals. The wire is high-quality, made in the USA, 18-AWG stranded.
