I own a 78 CJ7. When I purchased it the vehicle was in shambles. The heater was completely unhooked and laying in the back seat( whick was also completely removed and laying in the trunk). I replaced the tub and went to put the heater back in and ran into problems, I cant figure out the wiring for the heater and cannot find a good diagram in Chilton or Haynes. I have a 3 prong female end connector which appears to have a connection on the air duct where it connects with the heater. This connection seems to have a thermostate type spring on the inside of the air duct but no wires. A little curious since it has 3 wires leading to a thermostat. I think that there is a power connection on the engine side of the blower motor but Im not sure. Any help would be greatly appreciated. My wife keeps saying- in this winy voice "you know I dont think it will pass inspection with out the heater working, I know Im not going to get into it, what happens if it rains and your windshield fogs up and you crash". I say "your not going to get into it ehh? Promise? Anyways I m trying to make this as "wife friendly" as possible any suggestions on that topic would be grewatly appreciated also. Thanks fellas.
