Hi, i bought a use bobcat 753 older model and had to fix a few things... had problems with my shutoff solenoid and got it fixed thanks to this forum. while i was working on the solenoid problem i found 3 lose wires/plugs that are not pluged in into anything and i dont know where they go... maybe you guys can help me... here is the first wire of the 3, the other two come later when i get home: http://tinypic.com/r/264ic1f/5 also when i put the key in run position it shows me the hours, fuel 2(bad fuel sender, will get the sender on friday and replace it) then glow and then it shows me C-7 what is c-7 standing for? is it a error code?

There are normally several unused plugs in the wiring harness for accessories that can be field installed.
There are 2 Boss codes close to C-7 is EC-7 for engine coolant temp sensor out of range and HC-7 for hydrostatic fluid temp sensor out of range. So one of the loose plugs could be for the sensor.

There should be a sensor on the left side of the filter housing. Make sure there is a wire on that. That harness on my 763 goes under the filter head
