📝 Item Description

Genuine OEM Maserati 4200 GT and GranSport (M138 platform) luxury sports coupe interior roof/dome light central dimming and timer control module micro-ECU. Manufactured in Germany by Webasto, this module acts as the central computer managing the vehicle's overhead body electronics, including the courtesy fade-to-off illumination logic when doors open/close, delay timing circuits after ignition off, and parasitic battery drain protection logic. The plastic casing and integrated mounting flanges are fully intact. The multi-pin terminal sockets are perfectly clean and entirely clear of corrosion or short-circuit thermal melting.

⚠️ Condition & Fitment Notes

• Condition Note: Clean salvaged part. Marked with a yellow inventory marking dot on the plastic casing. Both mounting ears are structurally sound. It allows you to snap your vehicle's original factory wiring harness directly in for a straightforward installation.

• Ideal For: Replacing a failed or aged timer control module causing notorious early-2000s Maserati electrical ghosts, such as interior dome lights remaining stuck on permanently (causing battery drain), complete overhead reading lamp failure, or flickering dimmer relay logic.

• Important Note: Please cross-reference the molded stamp 626.20 on your existing unit and verify the specific plug pin-out configuration prior to purchasing to guarantee a flawless plug-and-play match.

🛡️ Warranty

• Warranty: 1-month replacement warranty covering control unit electronic component and delay timing logic faults.
