Big connector behind the switches to the right of the wheel is the lock/unlock for c/l Larger connector further back is the controller for the C/L, then theres two connectors in each door for the e/w and c/l.
Window controls live in the doors.
You may also have depending on your model, switches for rear wash/wipe and heated rear window, which have connectors. The haynes manual for the Vitara is a bit pish :(
