97 dx with z6 intake got all the vacuum lines hooked up but confused on coolant lines. using the y7 tb so there is the coolant taps on the bottom of the tb i know one is coolant in and one is the coolant out but what is the routing prior to and after this ( coolant comes from block where, goes to tb and goes back to the engine how?) i just need the route and i can figure it out please help:(

Lines run from the thermostat housing (on the block) into the iacv (on back of intake) then out of the iacv and into the throttle body then out of the throttle body and into the intake manifold (near the heater hose).

I bypass the IACV and throttle body coolant lines on all of my cars.
