The original owner of my car had fitted a dash switch and when I used the car daily in traffic I'd just flick it on if I got caught in a jam, otherwise it wasn't needed. All that's happened in my ownership is to rewire and fit a relay in the circuit, plus of course changing the fan for a more modern unit. When I tidied up the radiator 10+yrs ago the old switch was still there but all it's doing is keeping the coolant in.
If you really do want automatic control and can't fit the OEM switch then aftermarket fans such as the Kenlow I have on the Elan came with a bulb sensor & leads which you could slide into the top hose. There is a small rubber moulding, hard to describe but mine is a sort of half circle with indentations for the wire. This sits on the alloy thermosat housing outlet and the original hose slides over the combination and seals very well. You can set the temperature you want it to come on and it also has an override switch with a light to tell you when it's on. The original fan has long since been replaced by a slimmer, modern unit but the controller is still in there.
