Word-for-word from the 700/900 FAQ:

Cluster Removal:

Caution: Before you remove the cluster, disconnect the battery negative so that any contact between the rear of the cluster and the metal surround will not result in a short and a fried circuit board.

740 Instrument Cluster Removal. It's very simple. Place the turn signal and wiper stalks in the down position. Take a super slim screwdriver and remove the small plastic cap surrounding the small clock set knob on the left and the cap surrounding the dash light dimmer on the right. Under each of these is a phillips screw. Remove and pull the whole cluster out. Don't even need to remove the steering wheel. If it 's the first time out, the wiring will be held in tight behind the dash by plastic ties. You can cut these ties which will afford you enough room to twist the cluster around and replace any bulbs etc, or mark each electrical plug and unplug enough of them to give you the room you need.
