Proper installation ensures correct sealing, grounding, and signal functionality.
Power Off: Disconnect battery negative terminal before starting.
Inspect Mounting Area: Clean any rust, dirt, or old sealant from the chassis.
Check New Unit: Verify lens clarity, gasket condition, and wiring integrity.
Compare Old vs New: Confirm identical function layout (e.g., fog light position).
Remove existing tail light by unscrewing 2–3 mounting bolts/screws.
Unplug the multi-pin electrical connector carefully.
Install new WG9925810001 onto the chassis — align with holes and press firmly to seat the rubber seal.
Secure with stainless steel screws (torque: ~5–8 Nm).
Plug in the electrical connector until it clicks — ensure locking tab engages.
Restore power and test all functions:
Tail light ON
Brake pedal pressed → bright red brake light
Turn signal activated → flashing amber
Reverse gear engaged → white reverse light
Rear fog switch ON → red fog light
