6098-6948 — 8-Pin Female Unsealed Automotive Connector (Sumitomo HM Series)
Part Number: 6098-6948
The Sumitomo HM (High-density Multipole) connector series is one of the most widely deployed automotive wiring connector families in Japanese vehicle manufacturing. The 6098-6948 is an 8-pin female unsealed connector from this series, used extensively in interior, underdash, and body control wiring harnesses where environmental sealing is not required but reliable, high-density pin retention is critical. Found across Toyota, Honda, Nissan, Mazda, Subaru, and Mitsubishi platforms, this connector is a staple of automotive harness repair and replacement work worldwide.

Common Applications
The 6098-6948 is used across a broad range of vehicle systems where a compact, high-pin-count unsealed connector is required:
- Body Control Module (BCM) connectors — interior lighting, door lock, window control circuits
- Instrument cluster wiring — gauge cluster harness connectors on Toyota and Honda platforms
- HVAC control unit connectors — climate control module wiring harness
- Airbag / SRS module connectors — secondary harness connections (non-squib circuits)
- Power window / door mirror control — door harness junction connectors
- Audio / infotainment system wiring — head unit harness connectors
- Transmission control module (TCM) — interior harness side connectors
Vehicle Compatibility
The Sumitomo HM series 6098-xxxx connector family is used across virtually all major Japanese OEM platforms:
- Toyota / Lexus: Camry, Corolla, RAV4, Prius, Hilux, Land Cruiser, IS, RX, GS
- Honda / Acura: Accord, Civic, CR-V, HR-V, Pilot, MDX, TLX
- Nissan / Infiniti: Altima, Sentra, X-Trail, Qashqai, Navara, Q50, QX60
- Mazda: Mazda3, Mazda6, CX-5, CX-9, MX-5
- Subaru: Forester, Outback, Impreza, Legacy, XV/Crosstrek
- Mitsubishi: Outlander, Pajero, Eclipse Cross, L200/Triton
- Suzuki / Daihatsu: Swift, Vitara, Jimny — shared Sumitomo harness architecture
Why the HM Series Connector Fails
Despite being an unsealed connector, the 6098-6948 is exposed to the full range of automotive environmental stresses: thermal cycling, vibration, and in underdash applications, occasional moisture from HVAC condensation or water ingress through door seals. Over time, the dual-latch retention fatigues, terminals develop fretting corrosion from micro-vibration, and the housing becomes brittle from heat exposure. Intermittent electrical faults in BCM-controlled systems — random window operation, flickering gauges, erratic door locks — are classic symptoms of a degraded HM series connector. Replacement is the definitive fix.
Global Market & Regional Notes
Sumitomo Electric Wiring Systems is the world's largest automotive wiring harness manufacturer, supplying OEM harnesses to Toyota, Honda, Nissan, and virtually every other Japanese automaker. The HM series connector is consequently found in vehicles across every major market: Japan, USA, Canada, UK, Australia, New Zealand, Southeast Asia (Thailand, Indonesia, Malaysia, Philippines), the Middle East (UAE, Saudi Arabia), South Africa, and Eastern Europe. Auto electricians and harness repair specialists in all of these markets stock the 6098-xxxx series as a core inventory item.
Installation Notes
- Use a Sumitomo HM-series terminal extraction tool (flat-blade pick, 1.5mm) to remove terminals without damaging the housing
- Inspect terminals for fretting corrosion — lightly abrade with a terminal cleaning tool before re-use if corrosion is minor
- Confirm wire gauge before selecting replacement terminals — HM series terminals are gauge-specific
- Apply a small amount of contact grease to terminals in high-humidity environments
