I've got an open line, that I assume used to be connected to something, but I can't figure out where it used to connect. It's in near or between the brake and power steering fluid reservoirs. It's visible when looking under the front drivers wheel well, where it T's up it is not connected to anything. There is tape on the end of the line. I've got the FSM, but I'm not sure what system it's a part of yet, just knowing the might set me in the right direction. Do any of you recognize it off hand?
