a. nR = n wires in a ribbon (flat) cable; nW = n wires in a wire harness
b. If you are replacing an old LED board wire harnesses with a current version (N5225-60001), both wire harnesses must be
replaced. You must also replace the old test set front plate with a current version (2-port N5224-00004, or 4-port
