Download the 7845 Service manual that Asteral shared with us and you'll find great wiring diagrams in there. 7845 service manual.pdfDave's was my first choice without a doubt, but they're way backed up. Still, they're quicker than any known alternative.
There is a cover on top of the differential case, although I can't find it in the parts manual. Plus, there's other stuff mounted on it and it's under the seat, so there's a lot to dismantle even to get the cover off. The other way to take a quick size-up is to cut open the hydraulic filter. I'll do that when I receive the tractor.
On another topic in the parts manual, how about this wiring schematic? It's unfortunate that they didn't import the images as line drawings and instead rasterized them with a very coarse and useless resolution.
I don't do gaming gambling, but yes, I gambled on this tractor.

I did a quick check on the manual and the cover would indeed be the way to go but that's still a lot of stuff on top that may need to come out first.
