Install litronics - can you install self level too?

[23109VC]

I have a 2000 base with standard halogens. If I can find a car that has factory installed litronics - is there anything I would need to source from that car besides just the lights htemselves?

I am working on a deal where I may be able to buy the litronics off a friend's car - his car is a '9 996 that came with litronics from the factory. We are working out a fair price - he is in the process of preparing to sell his car, and figures he'll sell me his lights, and pocket some extra cash before he sells hte 911.

anyway - if this materializes,and I get to buy these - can I also "harvest" whatever electronics run the self leveling feature, or is that soething that canno be installed int omy car?

just curious as to what I can and cannot transplant off the car with regard to the lights.
