- Ensure the Neutral assurance bracket (2) is in the proper position on PNP switch (1). See Fig 1.
- Make sure the selector shaft is in Neutral as follows: Place a wrench on the selector shaft flats and rotate the shaft to its furthest clockwise position. Rotate the selector shaft counterclockwise two detents.
- Align the PNP switch (5) with the main housing so that the Neutral assurance bracket is facing outward. See Figure.
- While maintaining the correct PNP switch-to-selector shaft alignment, slide the new PNP switch (5) over the selector shaft (4).
- While holding the neutral assurance bracket in engagement with the PNP switch, install the two bolts (6) so that the PNP switch may be rotated with some effort. Tighten the two bolts (6) to 20 ft. lbs. (27 N.m).
- Remove and discard the Neutral assurance bracket.
- Reinstall shift lever (2). Install nut (3), by hand, on the end of selector shaft (4). Use a wrench (1) to keep the shift lever from rotating. Tighten nut (3) to 18 ft. lbs. (24 N.m).
- Reconnect the shift selector linkage/cable to the shift lever (2).
- Connect the external wiring harness to the PNP switch.
