The peanut gallery here is pretty rough, but if you want to please them, refer to the other two methods.
As an a/c guy, I prefer the cooling fan pressure switch grafted into the condenser or liquid line previously mentioned. The Derale fan controller with a probe would be second.
The reason I like those two approaches better is because they are not dependent on driver input. They activate the fan automatically depending on pressure or temperature. As previously discussed, as the pressure rises, so does the temperature of the condenser.

I really appreciate all the input. I really do. No doubt the pressure switch is the best way to go. BUT, that requires recovering the R-12 and opening some connections that are factory sealed from 1986. I have flushed the condenser several times over the years when I replaced a compressor. I have never removed the liquid line from the condenser to the orifice tube. I know that is not a big deal, just another place for a new leak.
I was hoping to do this the lazy man way and just add a relay. I have owned the Elky since October of 1991. It is my daily driver. I have personally driven it 280,000 miles. I know the car. The AC has operated the same way since 1991. It is not a major inconvenience, but it is annoying. My Elky operates better in every way than when factory new. With a 4 speed lockup transmission, limited slip rear end, a fuel injected 350 and numerous other improvements over the years. If my fairy god mother came along and said she could wave her magic wand and make it just like it rolled off the showroom floor I would punch her in the face and break her wand.
If I take off the liquid line and take it to a local AC shop I presume I can get them to splice in a T connection for a high pressure or temp switch. I would for sure would like to have a inline filter added. There is always some minor gunk on the orifice tube every time I replace it. I guess the T connection would have a Schrader valve so I can change the pressure switch without recovering the refrigerant.
