Pin*bot topper wiring

[maroguk]

I recently picked up an original Pin*bot. It came with the topper separate with no lights/wiring on top of the backbox although there are a few faint screw holes that may have once been mounting points. In the top face of the backbox is a hole that looks like the wires fed through and a 6 way female connector below which I suspect connects to the topper lights.

I was hopping someone could help me understand how the topper lights are mounted and wired up? Pictures, diagrams, circuit diagrams etc. would be appreciated.

Thanks
Steve
