1990 5.8 heater core?

My heater core has been removed by previous owner. Is it under the glove box in cab?
There are no lines in engine compartment see photos



Are there 2 lines that are supposed to go to a plastic reservoir (see next photo)

The box on the frame rail is the carbon canister to capture fuel vapors from the fuel tank. Definitely do not hook up heater hoses to that. You access the heater core by removing the glove box. There will be several bolts to remove once you get the glove box out of the way to allow you to remove the cover over the heater core.

Thanks

Do the 2 heater hoses from the firewall go straight to the water pump?

Just by memory, one goes to the water pump and the other to the outlet at the front passenger side of the intake manifold.
