DJ70110-6.3-21 Automotive 1-Pin 6.3mm Black Female Connector — Wiring Terminal Replacement
The DJ70110-6.3-21 is a 1-pin black female automotive connector in the 6.3mm terminal series, designed as a direct OEM-compatible replacement for damaged or corroded wiring harness connectors. The 6.3mm terminal pitch provides robust current-carrying capacity for moderate-to-high current automotive circuits, while the PA66 nylon housing withstands continuous underhood temperatures and exposure to engine fluids. Available individually or in multi-pack quantities for workshop and fleet maintenance use.

Why Replace Automotive Connectors Promptly
- Corrosion causes resistance — a corroded terminal increases contact resistance, causing voltage drop, intermittent faults, and heat buildup that can damage wiring insulation
- Cracked housings allow moisture ingress — even unsealed connectors rely on the housing to direct water away from terminals; a cracked housing accelerates corrosion
- OEM dimensions ensure proper mating — aftermarket connectors with incorrect dimensions create loose connections that arc and fail; DJ-series connectors are manufactured to OEM mating specifications
- 15A rating for versatile use — the 6.3mm terminal handles ignition coils, fuel injectors, sensors, and moderate-current actuators from a single connector type

Frequently Asked Questions
Q: What is the mating male connector for DJ70110-6.3-21?
The mating male connector is the DJ70110-6.3-11 (or equivalent OEM male plug). The “-11” suffix denotes the male (plug) version; the “-21” suffix denotes the female (socket) version in the DJ series naming convention.
Q: Can I use this connector for a fuel injector circuit?
Yes — the 6.3mm terminal is rated for up to 15A continuous, which is well above the typical 1–3A draw of automotive fuel injectors. Ensure the wire gauge matches the circuit requirements (0.5–1.0mm² / 20–18 AWG for injector circuits).
Q: How do I remove the terminal from the housing if I make a mistake?
Use a terminal removal pick (also called a terminal release tool) to depress the locking tab inside the housing cavity while gently pulling the wire. Do not use excessive force — the locking tab is designed to hold the terminal securely and requires the pick to release. Terminal removal tools are available in automotive wiring tool kits.
