Got a Citroën/Peugeot electric pump for my Citroën. 3 wires to hook up (power, ground, and a switching wire to the relay mounted on the pump, heavy fuse is included). Later models have more electronics, to make it speed-variable. I suppose you could make it user-adjustable and/or turn off at the dash.

On the upside, unlike the belt driven power steering on my other car, this one seems to freely let the oil flow forward when the pump is not running, steering just reverts to manual heavyness, instead of nearly-locked-solid like the mechanical pump.
