Three wires volition demand to live cutting inwards the electronics box together with soldered to 3 conductors inwards the RJ-45 cable.

The 3 wires control:
  • Ground connexion to switch into tiptronic
  • Ground connexion to upshift piece inwards tiptronic
  • Ground connexion to downshift piece inwards tiptronic
The next diagram shows these 3 solid soil paths. When the shifter is moved over into tip, the switch labeled "engage" moves over together with grounds the path from the TCU to ground, energizing tiptronic. When the operator moves the shifter to upshift or downshift, it grounds that leg of the circuit from the TCU to ground, causing the shift.

These 3 wires are terminated inwards the electronics box at ii 10 pivot connectors, T10b (10-Pin Connector, yellow, connector station electronic box plenum chamber) together with T10 (10-Pin Connector, blue, connector station electronic box plenum chamber).
