My taps don't have microswitches fitted?

I have a 1982 Mustang Shetland GTS, and the taps fitted do not have micro switches fitted like the more modern style. I guess it just uses the water pressure through the Shurflo water pump (internally mounted, not a submersible type)

The taps are getting a little stiff now so I thought about replacing them with more modern types, but would they then need the microswitches wiring in to the pump, and if so any ideas how the wiring should be done

I am a competent DIY'er, just need some guidance on the principles i should follow
