The switch is on the transmission..It is usually a dealer item but you can get one from Rockauto.com for about 1/4 of what the dealers charge.

Removing the Manual Lever Position (MLP) sensor

As of 1994, the neutral safety switch is referred to as a Manual Lever Position Sensor (MLP).
  1. Disconnect the negative battery cable.

  3. Disengage the harness connector from the MLP sensor.
  4. Remove the 2 sensor attaching bolts and remove the sensor.
To install:

  2. Adjust the MLP sensor then tighten attaching screws to 80-100 inch lbs. (9-11 Nm).
  3. Remove the jackstands and lower the vehicle.
  4. Connect the negative battery cable.


ADJUSTMENT

C6 Transmission
  1. Hold the steering column transmission selector lever against the Neutral stop.
  2. Move the sliding block assembly on the neutral switch to the Neutral position and insert a 0.091 in. (2.3mm) gauge pin in the alignment hole on the terminal side of the switch.
  3. Move the switch assembly housing so that the sliding block contacts the actuating pin lever. Secure the switch to the outer tube of the steering column and remove the gauge pin.
  4. Check the operation of the switch. The engine should only start in Neutral and Park .

Under dash driver side look behind the upper arm of clutch pedal and you should see a green and black wire coming from the button (switch) assembly on the firewall. The wires go up above the clutch pedal. About in the middle of under dash on the left side you should see a white connector these wires run to. Disconnect. I just had the problem and not only starts now but not stalling like it was but it's only been one day but tested it pretty good.

I think you are referring to the clutch pedal safety switch. If so it is located behind the clutch pedal under the dash.

1989 Dodge Dakota 2WD Auto Trans won't start in park


Thats right, it's a neutral safety. There is a wire running beside the shifting linkage at the tranny. It has to be broke or cracked. It may even have come umplugged. There is no safety issue though. I would feel comfortable with my son driving it. The biggest problem would be putting it in nuetral and it still not starting. Hope this helps.
