kbus...same thing...just tapped one
Got it. Checked the WDS and found that is a wire that goes to the wiper motor and the rain sensor taps into it from the factory as well. I ordered these "Posi-taps".. heard they worked really well:


anyways, I will tap into the K bus too if I don't have a port available. Only thing left is to grab some 18 gauge wire, fabric tape and the fuse terminal to use the Rain Sensor spot on the fuseblock... then, of course tear the pillar covers off, wire it, tuck it away then code it. blah! thanks for the help. I'll report back with the results!

Cheat Sheet:

GT1/ISIS/MoDiC = Factory authorized diagnostic system used by BMW dealerships across the world.

NCS Expert = BMW Factory R&D programming tool available on the internet (not intended for the public and not available to the dealership network)

OEM = Genuine BMW part only available from a franchised BMW dealership.

DME = Engine Management Computer
