MTroniks Super E Truck ESC

[Mountain]

I recently got an MTroniks Super E Truck off fleabay and it had no instructions.  I can download the standard ones for the Sonik 4 range which tell me how to configure the basic settings but I can't see any for the other features.

Does anybody know how the 4 Pin connector should be wired for lighting.  Also it came fitted with a diode wired between the battery terminal and one of the motors output is this a standard fitting or something that the previous owner has added.  And any reason why?

If anybody has a copy of the instructions is it possible to scan them?
