I was online to find out how to discount the VRO system. The dealer told me all you need to do is plug the oil line. I look online it said that to discount the wires off the VRO system and the wire off the oil pump. What are them wire for? I know that motor have a overheat warning system. I just want to make sure that is not part off them wire that I just discount. Thank you

Plug the oil line and unplug the wires coming from the pump.----------Find a tan wire from the temp senser on one of the cylinder heads.--------Ground the wire to the block with the key turned on.----This will test your overheat warning.------Reconnect the tan wire. --You are good to go.

What are the wire that are coming off the VRO pump with four wire.

That would be the " no oil " warning system.
