GLOW PLUG (THERMOSTART) KIT
All you need to supply is the wire. If your tractor did not come with a glow plug you will need to unscrew the factory plug located between the air filter & engine. This is where the thermostart unit screws into. All Yanmar tractors will have this pre-threaded hole for the thermostart to screw into. You will NOT need to drill any holes to install this kit.
