Ours are '08 and up. Well I took some shots to show you, on this pic http$://vvv.dropbox.com/s/l1dlol1yng6gbdx/DSCN0102.JPG
you can see where the mast cable attaches on the left side and black wires coming from the VM, notice the second from the top not being used, that would be the black wire. Then on the top of the scisssor http$://vvv.dropbox.com/s/hwl8n3id44eg2mm/DSCN0101.JPG
you can clearly see that black and blue aren't hooked to anything. We got all functions retract, extend, tilt, and S/S.
Just replaced $ for s, and v for w, to see pictures.
