I had to remove this panel (nuts in the wheel well/fender). Take a look at the pictures in my 1st post.
i dont understend, is that 2 sets of wires, the one under the panel and 9 pin connector? Or can i use one or the other?
Some tractors just have the connector (10 pin Metripak) behind the cab and others have a extension from there to the round grey connector (9 pin Deutsch) at the hitch/remote hyd. This extension cable has pin A to A, B to B etc.

Ok mine has the round grey one. So this is the connector thats called deutsch 9 pin?
I believe so
this is what my tractor shows when i plug in the wires but it doesnt movethe hydraulics automatically. What am i missing?
Check out Matt’s post above. You have to detent the scv finger tip to go into AC mode, and the tractor has to be moving to actually move the hydraulic valves.
Hah of course. 
Revisiting this and just wanted to add this screenshot from a tech manual for anyone reading in the future. It mentions needing between 2.25v and 2.75v immediately after power on and what AC and EC mean.
Also a PDF of the rear harness for an 8000 with the 10 pin metripack hidden behind the cover. The TouchSet harness extends this hidden 10 pin Metripack to a 9 pin Deutsch on the back of the tractor.
