• Motorcycle: Signal harness, ignition coil, fuel injector, and lighting connectors
• General: Actuator connectors, solenoid valve harness, exterior lighting circuits requiring IP68 sealing

3.5mm Pitch – Why It Matters

The 3.5mm terminal pitch is a mid-range spacing used in Hyundai/Kia sensor harnesses and many motorcycle ECU sub-harnesses. It is not interchangeable with 2.2mm, 2.8mm, or 6.3mm pitch connectors. Always verify the pitch of the original connector before ordering a replacement to avoid fitment issues.

Diagnosis – Common Faults

• Intermittent sensor codes after rain: Inspect wire seal integrity – a cracked or missing rubber seal allows moisture ingress and causes intermittent open-circuit faults
• Hyundai/Kia fault codes: P0115–P0118 (ECT), P0335 (CKP), P0500 (VSS) – check connector before replacing sensor
• High contact resistance: Measure with milliohm meter; >0.5Ω indicates terminal corrosion or spread – replace connector assembly

FAQ

Q: Is this connector compatible with Hyundai Elantra / Tucson / Sonata?
A: This 3.5mm pitch 4-pin waterproof connector is used across multiple Hyundai/Kia platforms. Confirm the housing profile and pin count match your vehicle's harness before installation.

Q: What is the mating male connector?
A: The mating male connector uses the same 3.5mm pitch 4-pin housing. Verify the male housing part number from your vehicle's wiring diagram or contact us for assistance.

Q: Can I use this on a 12V motorcycle?
A: Yes – the connector is rated for 12V/24V systems and is suitable for motorcycle harness repair in exposed locations.
