I have installed them. Physically installing the sills was the easiest part.
The electronics (a ballast and some wiring) install behind the passenger seat. The wires going to the sills themselves are actually low voltage AC, so after the ballast you don't have to worry about wire polarity. You have to get the carpet up, a special tool is required (or VERY carefully use a set of pliers) to remove the hold down's.
The center console storage box needs to be lifted (two screws requiring a deep 10mm socket to remove) to route the cable across for the driver side.
The instructions want you to strip insulation and solder/tape the new wiring into place, behind the access panel on p-side just above the air bag cutoff switch. This is the harness that routes up the p-side A pillar to the rear view mirror, dome lights, and Homelink buttons. There is only 1 hot wire for all three circuits, apparently those are activated by relays that supply a "ground" to the circuit (rather than supplying a "hot" to the circuit) when enabled. So you'll use the "hot" and the dome circuit "ground". The harness in MY car did not have anywhere near the amount of slack depicted, there was no way I was getting a soldering iron in there for a proper job. I ended up using two 3M quick connect's that piggyback one each new wire onto an existing wire without cutting it.
With the proper tools for getting the carpet and the console box up, the install would take less than an hour. Somebody else in here did the sill install before I did, and posted some pics and experiences in a thread. Try using the search tool and you should find it (if above hasn't scared you away from trying it yourself :!: ).
I was gonna do a VFAQ on this, but didn't have a camera when I was installing. :cry:
