With your advise I traced out the wheel sensor wires. There are plugs at each wheel. The front wheels also have plugs above them under the hood on the fender wells. The rear sensor wires attach to one plug above the rear end. I unpluged all wheel and secondary plugs. I used a ohm meter to check each wire for continuity, two wires per wheel. When I got to the left front success, no continuity on the white wire. I'll order a new wire from the "stealer"(I like that) and update later. Check out the picture the Cornfed lift looks great. Thanks again to all.
