hi i have changed my engine and intake at the same time. since that it run at 220 degee. 160degree termostat. im not sure how to plug everything on the right order. Heater rad/thermostat housing/2 holes behind lt-1 intake conversion/oil cooler rigid hoses/. and how the 3 way plastic splitter with a vaccum hose works?

the plan here dos'nt show the right emplacement for the plastic spliter and the oil cooler. Should i get rid of al that?
