Just curious, what are you trying to accomplish moving the VSV?

I'm guessing ease of access - that VSV is mounted underneath the Intake manifold from the factory: it's a PITA to get to. Moving it up onto the firewall makes access / diagnostics much easier. (BTDT here.)

Does your Camry have an OBDII port? IIRC, it will be behind the coin tray, on the left in the passenger cabin.
