4age refrigerated lubrication system

I need to find a technical diagram and hope for the manufacturer of the lubrication system with oil radiator as some 4ag (z) E brings to install it to a 4AGE that originally did not have it. The problem is that it occupies specifically knowing the lines as they are connected to the shot that has the base of the oil filter from which "they derive for the radiator" not to place it badly and lose it.
How does the radiator connect, in parallel or in series?
Does the system attached a check by pressure or by sense of fluid? etc...
