[QUOTE="mcatrophy, post: 1140430, member: 3187"] If it won't engage then it's a moot point whether it can "see" the brake signal in order to disengage. If it had engaged prior to the brake light failing, it will disengage for the same reason it wouldn't engage in the first place with a failed brake light, its detection circuit puts sufficient voltage on the wire to detect it's blown, nothing to do with where the brake lights get their power from. However, in the limit, I agree it's safest to use the signalling 12V supply for the CC, but only because a short circuit on the brake light wire would otherwise allow engagement and it would not "see" the brakes being applied. That short circuit would blow the signalling system fuse the next time the brakes are applied, so stopping the CC. Not a scenario that I am going to worry about sufficiently to change where mine is powered from :) [/QUOTE]
