Ok, for the 99 to 2001 engines... The term charcoal canister is way wrong. This thing is HUGE! its got so many inputs that I believe Evap canister is more appropriate.
Also, the canister is the same either way between 4cyl and 6cyl models of the Camry. SO, if anyone else chooses to go the route of hooking up the entire OBDII Evap system, you can get the whole box w/ all the spaghetti from either vehicle.
The other chore is going to be how to mount it. It has to be mounted horizontally. Otherwise it will leak into the tubes, or hold all the fluids as all the ports come out one side of the unit. It's at least 12-14" in length and 6-8" in width.
