Speed Sensor Installation Instructions

Automatic Vanagons

  1. Install the CV joint flange under the original plates and torque to specs.
  2. Bend the provided bracket to approximate photo by placing one end in a vise and with an adjustable wrench put a 90 degree twist in the part.
  3. Install the bracket with an 8mm bolt into the empty hole on the Vanagon Automatic transmission.
  4. Install the sensor into the bracket and adjust the gap from the sensor to the magnet to maximum of 1/16 inch. The sensor can be installed with the wires going in either direction.
  5. The center of the square area is the spot of highest sensitivity and should be aimed at the magnets.
  6. The black lead goes to ground, the red to ignition + and the blue to the ECU speed sensor terminal.
  7. Be sure to use a wire tie as a strain relief so that the wires into the sensor are protected.

FAQ

The 4-5 volts that should be present at the blue wire when the sensor is connected and the ignition is on is voltage from the ECU.

When operating correctly, the hall sender is activated by the magnets (south pole only) the sensor pulls the voltage at the blue wire to ground.
