Their on Amazon. Much better than original. Their sealed to start with. Gauges are somewhat generic. Power, Ground, Sensor and indicator light connections. You do have to splice on the proper connector for the harness your connecting to. I took connectors off original gauges and used a butane soldering iron with heat shrink attachment and some clever splices that have heat shrink insulation and solder integrated into one splice that seals from water. The tachometer uses pulses from the ignition on the sensor wire. Speedometer is GPS. I used some epoxy to mount the satellite antenna under the starboard side of the gauge cowl. I have not installed the gas gauge yet as the original works fine but the replacement has a much larger scale on the dial so I plan to replace in the future. The tank has a 90 ohm variable resister on the sending unit so you need to buy a gauge that uses that range. I put super bright lamps in the trouble light gauge and an led one in the gas gauge.
