 Guys, I'm stuck trying to find a home for a yellow wire in the engine bay on my 84 2.5. I believe it's the high speed a/c wire thats tied into the a/c somewhere but it was cut off about a foot from wherever it went. It is wired into the cooling fan temp switch on the front of the head, but as far as I can tell, there is only the compressor on/off green wire going to the compressor. Looks like 84 didn't have low or high speed shut-off lines wired in. That leaves me with a yellow line with nowhere to go. of note, even when I didn't have a compressor and just some cut ends remaining, the a/c button on the dash would still turn on the cooling fan. Anyone have any ideas? The shop manuals are strangely sparse for 84.

84 2 speed rad fan for AC cars,

Switch lives(lived) on back of compressor to run fan at high speed.
No switch likely = some fool replaced the compressor w/o a clue how to wire.------------------
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.

Thank you Ogre, very much appreciated. This may be the missing schematic I needed.
