Sorry about bumping an old thread.

When I added my DIC to my 01, I got the dimmer wire mixed with the chime wire, and mine wouldn't dim at night. I figured it out, but if you still want to cut a wire, take out your dic, and on the back, each wire is numbered on the plug. B1 should be a corner wire, it is gray in color, and if you cut it, the DIC will not dim. Your Eng/Met, Reset, Mode, and Trac/TCS button wont light either, so that may be a side affect, depending on who you ask.

Good Luck.
