There are two level sensors, one front, one rear. Both on the passenger side (US spec cars). I have not installed the autoleveling parts yet, but it doesn't look like a big deal.

The real challenge will be the wiring. The harness is not available seperately. I'll need to make this. I have a block diagram from the retrofit kit that deciphers the wiring - the sensors talk to the LCM and the LCM talks to the lights, but it looks like a major PITA to fish the harness where it needs to go.

Also, I'm fairly certain the stock (halogen) LCM must be replaced, I dont think it has the circuitry to interprit the signals from to the levelers.

Update: I'm using a generic 12v relay at the moment, but it only has one trigger for the coil (one pin of the LCM controls both shutters). I ordered a handfull of relays from the dealer and the correct contact bushings for the light module. When I get the parts, I'll finalize the install and post photos. Ideally the relay will have two triggers (85, 85A) and two load (87 contacts) and a diode across the coil.

It looks like the SMG relay might fit the bill, it should be here on Friday.
