I don't know if this is too obvious to state but all you do is...
1) Open the tailgate
2) Look on the inside face of tailgate for access panels to the brake/tail lights clusters (2 long narrow plastic covers)
3) Unclip the access panels
4) Spot the retaining nuts for the central rear light clusters
5) Remove nuts and catch light units as they fall off the tailgate!
Pimps - as we say up here.
