That's not rust, it's Canadian patina...

Could someone point me in the direction of a diagram showing coolant flow through the 3B.... I can't find one in the FSM, and search seems to bring up way too many results.

Looking for direction and possible places to tap into it.

do you still have your rear heater hooked up?

tap into that, then you can just make a loop to whatever you need off the rear heater lines
If you look at the 2 hose connections.....one comes out of the thermostat housing and one comes from the water pump.
The water pump is "inlet" (suction) and the thermostat "outlet" is pressure.

Should make sense when you take a 2nd look at it.
