JRready Deutsch DTM 2-Pin Connector Kit — 8-Set with Solid Size-20 Contacts, Wedgelocks & Seals

JRready ST6330-201 is an 8-set Deutsch DTM 2-pin connector kit with solid size-20 contacts, wedgelocks, and seals designed for reliable, waterproof electrical connections in vehicles and marine equipment.

This JRready kit supplies everything needed to assemble eight complete 2-pin Deutsch DTM plug-and-receptacle pairs for aftermarket wiring, repairs, or custom harness builds. The package pairs robust PA66 nylon housings with copper-nickel alloy solid contacts rated for typical 20–22 AWG wiring. Each connector set includes wedgelocks and seal plugs so you can finish durable, weather-resistant terminations right away.

How durable are the housings and terminals for long-term use?

The connector bodies are molded from PA66 nylon, chosen for mechanical strength, heat resistance and electrical insulation. Terminals are solid size-20 contacts made from a copper-nickel alloy and are specially surface-treated to improve crimp integrity, reducing the chance of cracking during assembly.

• PA66 nylon housings resist wear, corrosion and heat exposure.
• Solid size-20 contacts accept 20–22 AWG wire with 7.5 A continuous capacity.
• Surface-treated contacts improve crimp reliability and conductivity.
• Included wedgelocks and seal plugs maintain mechanical retention and environmental sealing.

What is included in the JRready ST6330-201 kit?

The kit arrives ready to assemble with every component needed for eight complete 2-pin DTM connections. That eliminates the need to source individual terminals, seals or retention devices for small harness projects or spares.

• 8 DTM 2-pin plug/receptacle pairs (DTM06-2S / DTM04-2P).
• 16 solid size-20 contacts (0460-202-20141 / 0462-201-20141).
• 8 wedgelocks for plugs and 8 wedgelocks for receptacles.
• 8 seal plugs for unused cavities or added protection.

Where are these connectors best used and how water-resistant are they?

Deutsch DTM series connectors are engineered for demanding environments around engines, transmissions and exposed vehicle areas. With proper assembly—contacts crimped correctly and seals seated—the connectors provide effective protection against moisture and contaminants in automotive, marine and powersports applications.

• Commonly used under the hood, on motorcycles, ATVs, and marine craft.
• Seals and wedgelocks help maintain waterproofing when assembled properly.
• Suitable for wiring exposed to vibration, grease and temperature cycles.
• Not intended as an immersion-rated submarine connector; designed for splash and spray protection.

How should I crimp and assemble the solid size-20 contacts?

Use a compatible size-20 crimp die and quality crimp tool to achieve a gas-tight connection and avoid damage. The contacts accept 20–22 AWG wire—strip to the recommended length, position the conductor and insulation in the correct crimp pockets, and apply a single, full crimp stroke.

• Use a Deutsch-compatible size-20 crimp tool or approved ratchet crimper.
• Confirm wire gauge (20–22 AWG) and keep insulation intact where specified.
• Seat the contact fully into the housing and lock the wedgelock in place.
• Test continuity and mechanical retention before final installation.

Who is this for: JRready ST6330-201 is ideal for technicians, DIY auto and marine enthusiasts, and wiring professionals who need a compact stock of reliable 2-pin Deutsch DTM connectors for repair, retrofits or new harnesses. If you build or maintain wiring that sees heat, vibration and wet conditions and you prefer robust, serviceable connectors, this kit provides the terminals, seals and retention parts to complete consistent, durable assemblies.
