Where does the coolant flow on a 2.0 2bbl intake return?

[borlax]

I bought a 1988 2.0 engine for my truck and don't know where the coolant flow tube on the intake is supposed to flow to. I had to just plug it and would rather not. I've searched and haven't been able to find anything. I have a Haynes manual. Thanks for any help

It runs to a TEE which ties it into one of the heater hoses so it can allow water to circulate under the intake (to help the engine warm up quicker in cold weather).
