RAP Problem

[bbnight3]

Hello. '09 NNBS GMT-900 ExtendedCab Sierra, non-bose audio system. I tapped into the yellow wire on the teal connector by the brake pedal to get a RAP signal to run to my amp. Worked great. that is until I was installing a different amp which has the turn on wire terminal and the ground terminal too freaking close together and I briefly grounded the that RAP wire I tapped into. It was momentary - quick small spark - didn't seem like much. Now that wire has 12V constant on it rather than turning off when the RAP normally does. Does anyone know what that wire is or what I may have done by accidentally grounding it? Is there any known way of fixing whatever I screwed up? Everything else in the truck seems to be working normally. Thanks for the help!
