Nategreat923 Posted September 15, 2010 Share Posted September 15, 2010 93 Legacy sedan. So I took a look under the dash (steering colum) to see that there are 2 big plugs that are not connected to anything. 1 is a black plug that is held into place by a screw and a yellow one thats hanging next to it. Are these supposed to be plugged into something. Link to comment Share on other sites More sharing options...
Platinum_Racing Posted September 16, 2010 Share Posted September 16, 2010 The plugs are most likely for factory options which your car is not equipped with. What trim level is the car? L? L+? LS? SS? My guess is one of the plugs is for the optional air suspension system. The other is probably for cruise control. Link to comment Share on other sites More sharing options...
Bdubs Posted September 18, 2010 Share Posted September 18, 2010 Those are more than likely the diagnostic testing plugs for the OBDI system. Leave them unplugged, they are designed to give out codes when you get a check engine light. Link to comment Share on other sites More sharing options...
