JRready Deutsch DTM 4-Pin Connector Kit — 4 Sets, Waterproof PA66 Housings & Solid Size-20 Contacts

This kit supplies everything needed to assemble durable 4-pin Deutsch DTM connections for vehicles, powersports and marine applications. The housings are molded from PA66 nylon for toughness and environmental resistance, while the copper-nickel alloy solid contacts accept 20–22 AWG wire and are rated for continuous 7.5 A each. The package is built to simplify field wiring and replacement, saving time when repairing or upgrading electrical systems around engines, transmissions or exposed harnesses.

How do these connectors hold up in harsh conditions?

The JRready housings use PA66 nylon, chosen for impact resistance, heat tolerance and long-term electrical insulation. Combined with sealing plugs and wedgelocks, the system resists moisture ingress and vibration-related contact loss when installed correctly.

• PA66 nylon shells for wear and corrosion resistance
• Included seal plugs to protect unused cavities
• Wedgelocks secure contacts against vibration
• Solid contacts with treated surfaces to avoid crimp cracking

What electrical specs and wiring sizes do the contacts support?

The kit uses size-20 solid contacts made from a copper-nickel alloy engineered for stable conductivity. They accept 20–22 AWG wire and are rated for a 7.5-amp continuous current per contact, suitable for many sensor, lighting and control circuits.

• Wire range: 20–22 AWG
• Continuous current capacity: 7.5 A per contact
• Special surface treatment to improve crimp integrity
• Solid (single-piece) contact design for consistent mating
