the vehicle harness, not at the park neutral position switch lead.

8. Remove the park/neutral position switch from the manual shaft.
Installation Procedure

2. Slide the switch onto the transmission manual shaft until the switch mounting bracket contacts the mounting bosses on the transmission.
3. Install the switch to the transmission with two bolts.
