Hey,
I'm retrofitting pre-lci adaptive xenon headlights and have already done the LM2 retrofit. Since I needed PT-CAN high and low to the light module pins 71 and 72 I tried tapping into the red/blue and red wires located near the light module wiring. The problem is that when I connect those wires to my LM2 the left front wheel speed sensor gets interrupted by my wiring and gives me an ABS error. Has anyone done the retrofit from pre-lci halogen to pre-lci adaptive xenon, and where have you obtained the PT-CAN from to the light module?

EDIT:
When my wires are connected the left front wheel speed sensor shows speed as 0 and other sensors work perfectly and after removing the connection it works normally.
