Anybody have a good wiring diagram?
Do I only need k-line and power?
If you pull a few more of the sensor leads from the green connector to ground, you won't be too annoyed by excessive warnings while you go about your testing.

You can pair the powers/grounds and k-lines together (powers can get paired, grounds can get paired. Do not actually connect the powers/grounds to each other).
