All I did was drill a 1.5 " hole on the left side of the cargo area about half way up, half way back and mounted a small circular light (top half chrome, bottom half translucent white) and connected it (+ and -) to the cargo light in the ceiling (just pop the light out). I removed the left side (top, side) of the rubber rear door seal and ran the wire behind this. Used vampire taps (the little red type with the female spade connector) to tap into ceiling light, used coat hanger to fish wire to new light. Light comes on with ceiling light. Very easy mod and small light throws enough light to see fine, looks good too! Took about 30 minutes to complete.
