DJ70112A-1-11 / DJ70112A-1-21 Automotive Male & Female Connector — 1-Pin with Crimp Terminals
The DJ70112A-1-11 (male plug) and DJ70112A-1-21 (female socket) are a matched pair of 1-pin automotive wiring connectors manufactured to OEM dimensions for direct wiring harness repair and replacement. Built from PA66 glass-filled nylon housing with tin-plated copper alloy crimp terminals, these connectors deliver reliable electrical continuity and mechanical retention across the full automotive temperature range of -40°C to +125°C. The positive-latch locking mechanism prevents accidental disconnection under vibration and thermal cycling — critical for underhood and chassis wiring applications.
Available as individual male or female units with matching terminal, or as a complete male + female set — giving you the flexibility to replace only the damaged side of a connector pair or rebuild both ends of a harness from scratch.

Why OEM-Dimension Connectors Matter
- Direct plug-in fit — manufactured to OEM mating dimensions; no modification needed to mate with the original harness counterpart
- Positive latch retention — audible click confirms full engagement; resists accidental pull-out under vibration and thermal cycling
- PA66 nylon housing — rated for continuous underhood temperatures; resistant to engine oil, coolant, and common automotive fluids
- Tin-plated terminals — corrosion-resistant plating maintains low contact resistance over the connector’s service life
- Individual or set availability — replace only the damaged side, or rebuild both ends of a harness from scratch

Typical Applications
- Automotive single-wire sensor connector repair (O2 sensors, temperature sensors, pressure sensors)
- Actuator and solenoid wiring harness replacement
- OEM wiring harness repair on passenger vehicles, light trucks, and SUVs
- Custom automotive wiring harness fabrication
- Aftermarket accessory wiring integration
Crimping Instructions
Use a dedicated automotive crimping tool (ratchet-type recommended) sized for the terminal’s wire barrel. Strip wire insulation to 5–6mm, insert into the terminal wire barrel, and crimp firmly. A proper crimp should be gas-tight and withstand a pull force of at least 20N without slipping. Avoid using pliers — an improper crimp is the leading cause of connector failure in automotive wiring repairs.
Frequently Asked Questions
Q: Will this mate with the original OEM connector on my vehicle?
Yes — the DJ70112A-1-11 and DJ70112A-1-21 are manufactured to OEM mating dimensions and will mate directly with the original counterpart connector on the vehicle harness. Verify the part number on your existing connector before ordering to confirm compatibility.
Q: What wire gauge should I use?
The terminal accepts wire from 0.5mm² to 1.5mm² (approximately 20–16 AWG). Match the wire gauge to the circuit’s current requirements — for most sensor circuits, 0.5mm² (20 AWG) is standard. For actuator and solenoid circuits drawing up to 10A, use 1.0–1.5mm² (18–16 AWG).
Q: Is this connector waterproof?
No — the DJ70112A series is an unsealed (non-waterproof) connector. For applications requiring moisture protection (underbody, wheel well, exterior lighting), use the corresponding sealed/waterproof variant with wire seals and a connector seal.
