Nissan Teana / Sylphy / Tiida / Qashqai 3-Pin 2.8mm Headlight Levelling Adjustment Connector – OEM DJ7037A-3.5-21 / DJ7036B-2.8-21
Direct OEM-specification replacement for the 3-pin wire harness connector used on headlight levelling (adjustment) motors across Nissan platforms. Cross-references OEM part numbers DJ7037A-3.5-21 and DJ7036B-2.8-21. Uses the 2.8mm contact series in black nylon housing — designed for headlight levelling motor applications on Nissan’s B-platform, C-platform, and J-platform vehicles where the headlight aim is adjusted automatically or manually via a dashboard control.
The 3-pin headlight levelling connector is located at the rear of the headlight assembly, connecting the levelling motor to the body harness. It is exposed to moisture from the engine bay and heat from the headlight assembly. A failed connector causes the headlight levelling motor to stop responding to the dashboard adjustment control, resulting in fixed headlight aim that may dazzle oncoming drivers or provide insufficient road illumination — a roadworthiness issue in many jurisdictions.
