4-Pin Unsealed Female Connector – Motorcycle & Automotive Signal Harness

A versatile 4-pin unsealed female connector for motorcycle, scooter, and automotive signal harness applications. Designed for use in protected, dry locations within vehicle electrical systems – inside instrument panels, under seat panels, within enclosed switch boxes, or inside ECU housings where IP-rated sealing is not required.

Key Specifications

• Pin Count: 4
• Gender: Female socket (with wire)
• Seal Type: Unsealed (for dry, protected environments)
• Wire Gauge: 22 AWG (0.3 mm²)
• Wire Length: 5.5 inches (140 mm)
• Housing Material: PA66 nylon
• Terminal Material: Copper alloy, tin-plated
• Current Rating: Up to 3A per pin (signal circuits)
• Voltage Rating: 12V / 24V DC

Applications

• Motorcycle instrument cluster and dashboard wiring
• Scooter ECU signal input/output connectors
• Turn signal and lighting control harness
• ATV and quad bike switch panel connectors
• Automotive interior control module signal wiring
• Aftermarket accessory harness integration (GPS, USB charger, auxiliary lighting)

Unsealed Connector – Maintenance Tips

• Apply dielectric grease to terminal mating faces during installation to prevent oxidation on tin-plated contacts
• Inspect annually for terminal oxidation in high-humidity environments
• Contact resistance above 0.2Ω on signal circuits indicates terminal oxidation – clean with electrical contact cleaner before replacing
• For exposed locations subject to water spray, use the waterproof sealed equivalent instead

Frequently Asked Questions

Q: What is the mating male connector?
A: This female socket mates with the corresponding 4-pin male plug in the same connector series. Verify the male housing part number on your vehicle harness before ordering.

Q: Can I use this connector for a 12V power circuit?
A: The 3A per pin rating is for signal-level circuits only. For power circuits (lighting, motors, relays), use a connector series rated for higher current – such as the 2.8mm Metri-Pack 280 (13A/pin) or 6.3mm Faston series (20A/pin).

Q: What crimping tool is needed?
A: Use a precision ratchet crimper rated for 22 AWG (0.3 mm²) – Engineer PA-09 or equivalent. Standard automotive crimpers are too large for fine-pitch signal terminals.
