Remove traveler wire to IN stud relay board and in dose not pick but then car still levels down..two things why do u have feed from IN SWING RETURN to from IN stud block to controller in witch is connect to INB in controller and in turn pick relay IN taking it off inspection and why still leveling down?? Got me stumped is it in programming?
