RB26DETT coolant routing questions.

The basics:
No heater.
Grex remote oil cooler/thermostat plate.

Do 1 and 2 have to be connected if I'm deleting the heater and running a thermostat plate? Is there a way for the coolant from the rear to get to the neck internally? Can 1 and 2 be blocked?

If they must be connected, what is a good size tubing or hose to use?
