Installation Recommendations
Before any work, always disconnect the vehicle battery and follow the vehicle manufacturer’s recommended procedures. Typical replacement steps for a competent mechanic or experienced DIYer:
- Disconnect the battery and wait a few minutes to ensure electrical systems are fully powered down.
- Remove seat trim panels and access the switch/control module location on the seat side or base.
- Carefully unplug electrical connectors, noting any retaining clips. Avoid pulling on wiring harnesses.
- Unscrew or unclip the existing controller and fit the replacement unit in the same position.
- Reconnect connectors, reassemble trim panels, reconnect the battery and test all memory functions and seat adjustments for full operation.
Exercise caution near occupancy sensors, seatbelt pretensioners and airbag wiring—do not cut or disturb these circuits. If the vehicle requires coding or adaptation of the memory function after installation, this should be performed with appropriate diagnostic equipment.
