Ive got a '90 with sr20det. trying to install a previously removed (p.o.) heater core and hoses, but do not know the correct routing to make it work..

also, the climate control needs installed (missing).. i see two plugs in the dash and a cut wire cable.. what does the cable control? defrost/vent or temp? If temp, what turns the heat valve on/off (open/close)

Got it.
