5-Pin 0.7mm Unsealed Female Connector – Motorcycle ECU Harness Sumitomo 6098-3810

Direct-fit replacement for Sumitomo part number 6098-3810, a 5-pin 0.7mm pitch miniature unsealed female connector used in motorcycle ECU sub-harness, instrument cluster, and body control signal circuits. The ultra-fine 0.7mm pitch enables high-density signal routing in space-constrained motorcycle harness locations.

Sumitomo 6098 Series – Naming Convention

The Sumitomo 6098 series covers miniature unsealed connectors with pitches from 0.6mm to 1.0mm used across Honda, Yamaha, Kawasaki, and Suzuki motorcycle platforms. The suffix -3810 identifies the 5-pin 0.7mm variant. The 6098 series is cross-referenced with Yazaki 7282/7283 miniature series for some applications – always verify the pitch and pin count before ordering.

0.7mm Pitch – Critical Handling Notes

• Crimping tool: Requires a precision micro-crimper rated for 0.2–0.3 mm² (22–24 AWG) – standard crimpers will crush the terminal
• Wire stripping: Strip no more than 3mm of insulation – excess bare wire causes short circuits between adjacent 0.7mm-pitch terminals
• Not for power circuits: 0.7mm terminals are rated for signal circuits only (max 1A)

Compatible Applications

• Honda / Yamaha / Kawasaki / Suzuki: ECU sub-harness sensor signal connectors, instrument cluster data connectors, body control signal circuits

Diagnosis – Common Faults

• Intermittent instrument cluster readings: Inspect 0.7mm terminal contact pressure – micro-terminals are prone to spread from vibration
• No TPS or speed sensor signal: Check terminal insertion depth – a partially inserted 0.7mm terminal makes intermittent contact

FAQ

Q: Is Sumitomo 6098-3810 compatible with Yazaki miniature connectors?
A: The Sumitomo 6098 series and Yazaki miniature series share similar pitch formats but are not directly interchangeable – housing profiles differ. Always verify the part number and housing profile match your motorcycle's harness before installation.
