Yesterday I was replacing the heater core, but I forgot to take a picture of where each hose went so now I’m not sure if I have the correct set up. I have 3 hoses total  
Hose 1 (upper heater core) goes- heater core :hose: engine  
Hose 2 ( lower heater core) goes- heater core :hose: heater valve restrictor :hose: engine  
Does anyone have a diagram or even better a picture of where each hose connects into the engine, the engine has 2 connections 1 upper and one lower, and I know it seems like common sense to use to put the upper heater core hose in the upper engine connection and the lower heater hose to the upper, but I don’t want to mess this up. Here are some pictures of my set up.
