Just wanted to say Hi to All, got a 2010 CTS Luxury, sharp, nice ride...Working that fog lite upgrade, parts coming in daily, putting everything together, looking for that BCM for lights and terminal 19 or 11 for the hook up. Understand now that it may be under the dash driver's side. Will pull panels later to find. If I'm in the right area please advise. Again, Hi to all and keep driving Cadillacs.
