6-Pin 2.5mm Series Waterproof Connector – OEM 12010975 / 1201579 | Automotive Harness
OEM-specification 6-pin waterproof connector in the 2.5mm terminal pitch series. Cross-references part numbers 12010975 and 1201579. The 2.5mm pitch is used in automotive harness applications requiring a compact, sealed connector for sensor, control, and signal circuits. Available bare or with 15cm pre-wired leads.
| Pitch | Typical Application | Current Range |
|---|---|---|
| 1.0–1.5mm | ECU signal circuits, CAN bus, MQS | <5A |
| 2.5mm | Sensor signals, body control, compact harness | 5–10A |
| 2.8mm | Sensor signals, standard automotive | 5–15A |
| 6.3mm | Ignition switch, relay coils | 15–30A |
| Pin Group | Typical Function | Failure Symptom if Corroded |
|---|---|---|
| Pins 1–2 | Power supply (+5V or +12V) and ground | Module / sensor completely inactive |
| Pins 3–5 | Individual sensor signal outputs to ECU / BCM | Sensor fault codes, erratic readings |
| Pin 6 | Secondary signal, diagnostic, or shield ground | Intermittent fault, diagnostic tool communication error |

Q: How do I confirm the terminal pitch of my existing connector?
A: Measure the centre-to-centre distance between two adjacent terminals using a digital calliper. A 2.5mm pitch connector will measure 2.5mm between terminal centres. Do not attempt to mate a 2.5mm connector with a 2.8mm connector — the terminal spacing is different and the connectors will not lock correctly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
