It is cable operated,as in no electric in the cab,just 2 cables,with metal rods inside,that operate the levers on the pump housing,the valves are all inside the housing.You could not adapt this to an electric soleniod unit.You would be better off selling yours,and buying a western powerpack with soleniods,I feel the cable setup is the better of the towo,although they are both excellent.We have a few of these westerns in our family,they have been indestructable,the only reapairs in 10-15 yrs of hard plowing has been cables,and one electric motor,thats it.I wouldnt let the cable setyup stop me from buying it,the biggest problem with cables,is when the controller is mounted in the center of the cab,the cables have to be pulled tight,this makes for a sharp bend at the pump housing where it exits,thats where the cable breaks every time.luckiy if the up down cable breaks,you can still raise the plow,you just cant lower it.It the cables have gentle bends in them,not tight ones,they will last for 5-10 yrs,tight bends,oneset a season,I used toi have to change them a lot.
