Electric fan and aluminum radiator questions 250 straight 6

So long story short, with the replacement of my old 250ci engine block, I changed the radiator & fan to an aluminum radiator and electric fan, and I upgraded the alternator.
I have a temp switch for the fan, but it comes on too late in my opinion (Reading on my meter says 120-130 C which would be 248-266 F when the fan comes on).
I don't want the fan to run permanently, but I also don't want to mess with the temperature switch.
I'm thinking that I should put a switch in the cabin and/or connect it to something like the brake lights.
Maybe there is something else I can connect it to in order to automatically turn it on/off?
Any thoughts/opinions?
