Working on tracing and labeling the wires in my conversion and I see this in the cupboard:

Whats is it? I have not yet traced it as I need to remove some of the wood work and it also looks like it goes behind the plastic body work and there is a massive screw and bolt coming out of the body (I think).
I have a bad feeling that I might end up stripping out the conversion to be able to trace all the wires

(Not something I want to do! Have ordered on of those endoscopes off ebay, maybe it will make life a little less frightening)
Many thanks!
