The DIY should be updated. MY2003 X5's with homelink have a different wire setup I guess, when I tapped the only green (olive green w/ a dark stripe) it only gave the V1 power when the lights were on. The white wire w/ a dark stripe gave switched 12V power. I noticed this because I leave my headlights on Auto (I had installed the hardwire kit in my garage) and as I was driving into the gas station the other day, my lights cycled on and off causing my v1 to kick on, then turn off.
