Throttle Body

[Rancor]

Hello all...
There are 2 line that come off the throttle body.
(pass side) and (bottom pointing to pass side).
What are they for and where do they go?

Originally they were hooked to feed points on the coolant lines running from the engine front back to the heater valve. They supplied coolant to the throttle body to aid in warm up.

Everybody generally unhooks them to remove the heat source from the T.B.
