- Feed the two-pin Molex wire under the seat assembly and to the AM3L control module.
- Reinstall the actuator housing with the four (4) 1/20 hex bolts and washers.
- Thread the actuator pin through the seat assembly frame and actuator head.
- After successfully threading the pin through the frame and head of the actuator, secure it with the cotter pin and washer.
