check the hoses where they exit and return on engine.
Valve could be shut off.
I shut mine off in summer....just opened it up last week.

They are open... but, where is the correct spot to hook them up?

We're gonna need more details as to what you are up against . If the hoses are disconected it was probably done for a reason, such as a leaking heater core but the heater core connections are on the firewall on the passenger side of the cab about midway up , they should be slightly different sizes , the hoses may be looped to keep dirt out, they should have hose clamp connections if this doesn't make sense we are going to need pictures of your problem.
Good luck
