Lighting Control Module - 1991 300ZX Z32

The Lighting Control Module (headlight timer unit) for the Z32-generation Nissan 300ZX manages the auto-off headlight function and door-ajar warnings. Located behind the passenger-side kick panel, this unit is secured by 10mm bolts and plugs into the body harness via an 8-pin connector. When sourcing from junkyards, target 1990-1996 300ZX models regardless of VG30DE or VG30DETT engine code, as the module is functionally identical across the range, though early 1990-1991 units carry part number 28550-30P00 while later production transitioned to 28550-30P01 with improved internal relays. Common failures include burned contacts causing battery drain or non-functioning headlights, often accompanied by melted connector housings. Before purchase, inspect the pigtail for heat damage and verify the unit clicks when the door pin switch is activated. Installation requires transferring the mounting bracket; late-model Z32s (1993+) may require minor bracket modification due to dashboard revisions. Always disconnect the battery before swapping to prevent short circuits in the sensitive lighting circuit.
