Non functioning Cruise control points to a bad harness pigtail on the Electronic Throttle Actuator. Common problem with this age car. I pulled mine apart and rebuilt the wiring and the car ran beuatifully after. Someone with a V12 site has a good DIY on rebuilding these.

Definitely get the serial number off the harness to check its age. Bad insulation can cause all sorts of havoc. Search on the site for plenty of threads discussing this.

For the ABS - is it possible the wheel sensors for the brakes are needing cleaing and or replacement?

Watching the thread since I am very likely to learn something from your troubleshooting.
