How to Disconnect Multifunction Switch

[rockkent]

I need to change out the Mulitfunction switch in my 1995 Suburban. It turns out it was easy to remove the steering wheel and covers to get to the switch. I'm baffled, though, by the underdash connector.

I'd appreciate pointers on how to unconnect the MF switch connectors without breaking the connector block.

Thanks in advance.
