What seems like forever ago, I posted this:

To make the memory seats work, you need to cut the gray wire on pin B6 of the Tilt\Telescopic ECU under the dash to the left of the steering wheel. Run 12v from a switched power source to the ECU side of the cut wire.
To get cruise working again, snip the black and white wire on pin 2 of the cruise ECU above the brake pedal. If you want the clutch to cancel the cruise, you'll need to wire it up the switch on the clutch pedal.
