Hello!

I've got a 2001 f4i gauge set (US) on my fireblade. Thing is the the temp gauge sender doesn't work with it so I need a temp gauge sender unit off an F4i. I've looked at the thermostat fiche but there appears to be three candidates all with differing part numbers.

37750-pc1-004 "sending unit"
37870-mbg-003 "sensor assy"
37870-krj-901 "sensor assy, water"

Can anyone confirm which is the part number I need and where it would be located on the bike. Seems the wreckers don't have a clue and are no help to me.

Thanks in advance.
