Long story short, removed the spindle fan and z axis cover on my late 2006 VF2 to replace the coolant hose that sprung a leak, and wasnt paying attention to which 4 wire connector I unplugged the spindle fan from.. There are two of them on a gold colored plate at the top of the Z axis..

By the way, the service manuals for these machines are pretty crappy, I feel like they were a waste of $100.
