Parameters + OE cross-refs: 6-pin Micro-ISO plug-in relay, 12V coil, normally-open contact, 30A continuous (standard Micro-ISO rating) with plug-in socket mount; replacement for OE 25230-7996A and superseded numbers 25230-79963 / 25230-79964 / 25230-C9963 / 25230-C9973 (verify by part number and pin layout before purchase). Specs and supersessions referenced from OEM/parts sources.
Operation & install location (general): Multi-purpose relay used by the vehicle to switch higher-current loads (A/C clutch, cooling fan, lighting, horn/locks/ECM circuits depending on model). Typical locations are the engine-bay IPDM/fuse & relay box and the interior fuse/relay box. Basic swap procedure: disconnect battery, open fuse/relay cover, match the 6-pin micro-ISO footprint, pull old relay straight up, seat new relay fully, reconnect battery. If the original relay is faulty, the associated system may not operate.
Additional Nissan legacy fit (enumerated years for long-tail): Compatible with Nissan 200SX (1984, 1985, 1986, 1987, 1988, 1995, 1996, 1997, 1998, 1999); Nissan 240SX (1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998); Nissan 300ZX (1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996). These fitments appear where 25230-7996A is specified as “Relay-Light”/multi-use; always match to your VIN and fuse-box chart.
Complementary OE parts (for related circuits): Often paired in the same fuse/relay box: 25230-79917 (common 4-pin relay used for trailer harness/HVAC/horn/window circuits on many models), 25630-79960 (horn relay), 25230-9F915 / 25230-7995A (radiator fan relay on select models). Listing these helps refresh multiple aged relays at once; select by VIN/diagram.
