I've got one, but it seems l have no pix. Nevertheless, its simplicity itself. I've got it mounted on the inboard wall of the battery box and its been sitting there quietly doing its job for several years. It just requires a source of 12v switched power for the switched circuits (all this does is turn them on and off, they still get power directly from the battery). IIRC half the circuits are switched and half are constant-on.
Here's a couple pictures of mine installed.
Not the cleanest installation - but some day I do plan to organize the wires.
The first one is a model# 70217 (all seven circuits powered when ignition on) this is installed in an Ex-Mod under drivers seat
Second picture are two #70207 (three constant - four ignition) installed in a 1997 NAS under passsenger seat.
