My 58 CJ5 did not come with a heater so I have collected the parts. My question is hookup, since I don't have a preexisting to view. On the controls, there are 3 cables. I know one goes to the diverter box under the dash for defrost (I assume the one labeled defroster) vs heat, one goes to the engine compartment to the fresh air box but which one, temp control or air control. And where does the other hook up? The blower motor and controls all came from same vehicle (a 60 or 61 I believe) and it has a red and a yellow wire but the switch has this white pigtail. Help and pics will really be appreciated. I'm thinking I'm still missing a piece. Walcks told me there was a manual turn valve on the heater hose on some of the later ones that allowed you to total shut off water flow for summer time, but that would not involve a cable. A pic of the engine compartment and under dash would really help. Thanks.
