1984 Midas Kingston on Chevy G30Your post is fine, but you should tell us the year, make, and model of your RV. That will help.
And also to a 120 VAC outlet/plug.Looks like someone's home wiring job, those colors are usually on a tail light wiring harness.
Nope sorry, the remote start wires are against the wall.The colors match to remote start.
Are you sure that the wires are connected to something in the Onan? Does the Onan start both locally and remotely? If it starts, does it supply 120V power to the outlets, microwave and probably the TV with the power cord not connected to outside power? With the generator running, is there any voltage between the 3 pins of that plug?I have a remote start connection also, that is not these wires.
