Ok guys, who has installed a "blackout" switch to disable your brake lights? I did this without any problems on my F-150 but my 2001 330i has a monitoring circuit (aka: Brake light test circuit) on the brake light switch. I once heard that the only way is to install a relay in the trunk to open the ground circuit from each bulb. Before I go that route, I was wondering if someone has conjured up a way to do it at the brake light switch itself since it would be a much cleaner mod. And of course this mod can't set any codes.

Ideas? Anybody? :idea:
