The wired should be simple you just need to find motor wires and splice in i do not know how to young is wired but my gx had bullet connectors already. So all i did was make a 2inch splice with bullet connectors and leads for the hour meter that way i did not have to alter factory wires. I would assume.....the yong has connectors of sorts to wire the motor. Pop the cover and post a pic i can tell you how to wire its pretty simple. With being wired to motor you are only clocking time when motor is running. The water pumps and fans will prolly clock time as the hour meters can be sensitive
