where does the "T" line attach coming from oil cooler? 

(one end to throttle body and other to heater inlet?????)

There wasn't any lines installed when i got car had been sitting for 9 yrs.

thanks for any help

Year, make, model, engine, tranny?

👀 Assuming your question is regarding the '85 in your profile, there is a fitting on the driver side of the engine block for a short hose to connect to the cooler. The other hose goes forward and connects to a metal line that attaches to a "T" hose coming from the heater hose on the pass side.
