Hoses

One goes to the heater, the other goes to the radiator.
But like I PM'd you leave it off it's worthless anyhow.

On my 350 TPI it's...

Intake manifold to TB, TB to heater control valve, heater control valve to heater core (firewall), heater core...behind engine...to T connection on passenger side, one hose from the T to heater control vave, other hose to oil cooler, oil cooler out to radiator.
