Take a regular phone cord (RJ-11) and cut the ends off with a nice 8"

wires (Red+Green L1) (Yellow+Black L2) attach them to the ethernet cable
in this order: (solder and heatshrink would be nice)

BTW, there are other ways if you don't want to strip wire. let me know.

When you do make the connections, use a "Western Union Splice"; not the
type you would make with a wire nut.

The wires are very thin on the jack wire, so you may want to get a 12'
cord and cut in half to practice. Once you perfected the stripping of
that cable and know how you're you are going to solder and cover, then
cut cable to desired 8" (or longer if you want the splice hidden on the
floor).
