ok, to extend the wiring first you can't just splice onto the wire. you must have a box [which you already have] and a old work plastic box. cut in the box where you want it above the baseboard. in the old box [halfway] up your wall, try to knock out one of the bottom knockouts. an angled screwdriver will pry the ko out. feed a piece of 14/2 romex down through this ko all the way to the new opening and leave about a foot out of the wall. strip back the jacket about 6 inches and fasten a wire clamp inside the old box. the screw is probably a 10-24. remove a ko in the new box and strip back about 8 inches of jacket. feed the cable into the new box and push the box with cable into the wall and fasten. install your outlet [ a gfci receptacle] - in the box halfway up the wall the silverish wire is the neutral (white) and the other is hot. make up splices and use wirenuts. fold the wires into the box and install a blank coverplate.
