Mercedes-Benz 2-Pin Ambient Light / Welcome Light Wire Harness Connector – OEM 3-929080-5 / 3-1355470-1 / A0245459926 / A2215450228
Direct OEM-specification replacement for the TE Connectivity 2-pin wire harness connector used on ambient lighting and welcome light circuits across Mercedes-Benz platforms. Cross-references TE Connectivity part numbers 3-929080-5 and 3-1355470-1, and Mercedes-Benz OEM numbers A0245459926 and A2215450228. Blue housing — a non-waterproof interior connector designed for low-current LED ambient and welcome light circuits.
Mercedes-Benz ambient lighting connectors are located throughout the interior — door panels, footwells, dashboard trim, and overhead consoles. These connectors are frequently damaged during interior trim removal for upholstery repair, speaker replacement, or ambient light upgrades. The 2-pin housing locking tab fractures when the connector is pulled without pressing the release tab, causing the ambient or welcome light to become inoperative. A failed ambient light connector produces a dead zone in the interior lighting that is often misdiagnosed as a failed LED strip or control module.

Q: My Mercedes ambient light stopped working after a door panel removal — is it the connector?
A: Yes. The 2-pin ambient light connector is the most common failure point during door card removal on Mercedes-Benz vehicles. The blue housing locking tab fractures when the connector is pulled at an angle. Inspect the connector before replacing the LED strip or ambient light control module.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
