I am replacing a gas tank from a 2006 wrecked Prius to a 2005. The only difference is that the 2006 tank has 3 connectors under the back seat hatch door while the 2005 only has 2 connectors? Could this be a California vehicle thing and am I safe in just connecting the 2 harnesses that I have? I live in VA with no emission's inspection in our area. It looks as if all wires will match up for the 2 existing harnesses.
