OK, total bonehead move here.
Feeling pretty stupid for this, but hope someone can help.
I removed the tail light from my 2008 K1200S to install a new bulb. However, I didn't mark which wires go where on the tail light connections. I guess I'm kinda used to just having self orienting plugs vs. individual wires (which I notice BMW corrected on the K1300S). Can someone please tell me how the wires connect?? The tail light connections are marked 54, 58, 31 and I have Red/Gray (Positive), Brown (Ground), and Black/Gray (Brake). Please save me the embarrassment of calling the dealer.
