Tool to remove backup switch

What tool is used to wrench out the back up switch on the ZF 6 spd? It looks too tight to access for standard sockets or wrenches.

Go to Harbor Freight and buy a set of offset wrenches. I forget what the exact size is for these, but a whole set is like $15. It's tight quarters in there, but that is all I needed to get the job done.

Removed the clutch slave cylinder, then used an oxygen sensor socket to remove the switch.

I had my brother take a 7/8 socket, center on the internal flats and then machine the outside of the socket for a .015" wall to the internal hex peaks. Fits onto the switch and removes old and installs new switch perfectly!
