If you have a start/stop switch on the generator itself, you can probably ignore these four mysterious wires as they're probably for a remote start panel, as stated, the functions of which are duplicated by the switch on the generator itself.
For what it's worth, the Onan generator I have (a different model) does use four wires for the remote switch: a ground, a start signal (that is grounded when the switch is pushed on the start side), a stop signal (grounded when the switch is pushed the other way on the stop side), and +12V power lead for the hour meter and running indicator light. (The switch is a single pole double throw momentary center off rocker switch.)
You do need to have +12V connected to the generator, I've seen on the starter solenoid, and chassis ground, and this needs to be a pretty hefty connection as the starter uses a good bit of current. Obviously there are also 120V connections for the power output.
