Specs & OE references — HFV9-G 12-Z-R; 12 V coil (124 Ω), SPDT 1 Form C contacts, 35 A continuous (13.5 VDC), operating temp −40 °C to 125 °C; sealed housing; 2.8 mm Micro-280 quick-connect terminals; internal parallel suppression resistor (R). Compatible with OE 23886398 (match by number & footprint).
Install location & operation — Plugs into Micro-280 relay sockets in fuse/relay boxes (engine bay or interior junction block). Standard 5-pin pinout: 30 (COM), 87 (NO), 87a (NC), 85/86 (coil); with resistor there is no polarity requirement on 85/86. Typical controlled circuits: headlight control, fuel pump control, horn, A/C compressor clutch, start/stop. Steps: disconnect battery → pull old relay straight up → align pins 30/87/87a/85/86 → seat fully → function-test circuit.
Fitment rule (how to confirm) — This is a Micro-280, 5-pin, SPDT relay. For accurate fit, match OE 23886398, the Micro-280 footprint, and the 30-87-87a-85-86 socket layout (22.5 × 15 × 25 mm body). Do not choose by model name alone; trim/market wiring differs. Compatible with any application that specifies HFV9-G 12-Z-R or OE 23886398 in a Micro-280 SPDT slot.
Durability & compliance — Extended-temperature design (up to 125 °C), dust-protected sealed construction, endurance rated to 1×10⁵ ops, vibration and shock tested; RoHS & ELV compliant. Built for demanding under-hood environments.
Failure symptoms this replaces — Intermittent/no-start (fuel pump relay), inoperative cooling fan or A/C clutch, horn/headlamp relay clicks with no output, burnt or heat-stressed relay body/terminals. Replace when the circuit tests good but relay output is inconsistent.
