I have a high beam malfunction, and I have found a broken wire on the BCM harness. I need the BCM pinout and connector description/color reference to trace it down.

See how far you get with these.

The second and third diagrams are blown-up versions of the first one so they're easier to read. The fifth and sixth diagrams are the fourth one cut in half and blown up.
