There are no sensors or magnets on the jacks. When on inspection at any place in the shaft, in the down direction TPDL and TPDR come high, in the up direction TP3SR and SL come high. Does not matter where in the shaft the car is those come high depending on direction.
In IMS row 9, line 1 has TPDR, Line 2 has TPDL, line 3 has TP3SR and line 4 has TP3SL. How does that correlate with the cons on the 188 e board? Con 9 on the 188e board does not have any wires in it.
