Contacted local Porsche Dismantler whom assured me there is nothing else to buy. Lights are straight forward install plug and play on any Boxster from 1998 to 2004. Nothing else to buy. The "control boxes" are attached to the rear of each light. Everything needed is attached to these.
By the way; Porsche Dismantler had another used pair to sell for $1800.00! Get 'em here for half price..
