The wiring on my leveling system was all messed up when I bought it. I am trying to figure out the wiring schematic for the tag switch. It appears that current from the switch activates the lowering valves on both axles (they are wired together) and a seperate air valve blocks the air supply to the tag manifold. I cannot see how this would work unless there is a diode installed in the harness to prevent the main axle lower air valves from opening. Can somebody help me by explaining how yours works. I have talked to Newell ...they have sent schematics to me but the tag axle is not included and the wire colors on their sheet are not the same as mine...I have had to trace each one out....It seems to be leveling properly now.
