I'm trying to hook up an analog tach to my DF 300 Suzuki. The previous owner removed all of the gauges .The wiring harness operates the electric shift control box and push button start switch. I cant find any wires to hook to the 4 pin connector on the tach or the yellow,gray or black wires. Do I need to install an additional wiring harness to hook this tach up to? Any help will be appreciated..
