Fuel Tank sending unit w/gauge removed from an 03 600HO. Good condition. Gauge shows signs of light fire damage...wires are melted a little...not bad. Gauge will work on 02 03 04 Rev...maybe 05...not sure when they changed the wire harness. You need a Grey 3 wire plug near the tach connector under the console...see pics. Sending unit will work with the new wiring...05 06 07... but you will need a different gauge.
