Coolant hose to TB ?

Just by pass the TB think about 2ft of heater hose will work, that way don't need a mess of fittings.

The early models pre-93 have it, best reason I can come up with is to stabilize intake charge.
 
its for warming the incoming air only needed for winter time up north down south in summer time its best to bypass it don't need to warm the incoming air its hot enough here is a tip after you bypass it put a hose on the TB run down under to front of car put a small funnel on it for cool air to go up and around the TB to try and cool the incoming air charge. with the coolant running though the TB after the car has warmed up feel how hot the TB is it will burn you after you bypass it then feel it it will be cool to the touch:)

pretty close. ford, along with other manufactures had thought back then(fuel injection being a somewhat new concept) that the warm water will prevent the throttle body from freezing and possibly staying open. later learning that it wont freeze anyways everyone stopped doing it.

as a possible project idea for this summer im thinking of pluming lines down to a large tranny cooler off of those ports just to see if it adds additional cooling. have a fan set to it rigged to run off of a relay system for when the a/c is engaged only due to the engine tends to run a lil warmer with the a/c and that might help to balance it out.
