    Heater Core to Engine Hoses, which goes where?

    Hey all!
    So I'm putting wraps to my S52 swap. The PO recirculated the coolant within the block but I'd like my car to have heat because I enjoy leaving the top down on those fall nights as they turn cold.

    Can anyone clarify which hard heater core hose coming out from the firewall (upper/lower) goes to which corresponding outlet from the motor (rear-most/front-most)? And also, where should I get those hoses?

    I'll post a picture tonight to clarify what I'm attempting to do but if someone understands just by reading this, then awesome!

    The bottom hose goes to the back of the engine/head. The top hose goes to the front of the engine/reservoir.
