JRready Deutsch DTM Connector Kit 2–3–4–6–8–12 Cavity — 54-Pair Size‑20 Nickel-Plated Terminals & PA66 Housings

JRready ST6484 is a complete Deutsch DTM connector kit that supplies 2, 3, 4, 6, 8 and 12-cavity housings, 54 pairs of nickel-plated solid size-20 terminals, seals, wedgelocks and a removal tool for reliable automotive and industrial wiring.

This kit bundles the core parts technicians and DIYers need to build or repair Deutsch DTM harnesses: durable PA66 nylon connector bodies in common cavity counts, matched solid male and female size-20 contacts for 20–22 AWG, sealing plugs to close unused cavities, wedgelocks for retention, and a compact plastic removal tool to extract stamped contacts without damaging the connector. Parts are broadly compatible with standard Deutsch DTM systems, and the nickel plating on the solid contacts enhances wear and corrosion resistance for long-term electrical contact integrity.

What exactly is included in this DTM connector kit?

The ST6484 kit contains connector housings in 2, 3, 4, 6, 8 and 12 cavity configurations along with wedgelocks and sealing plugs to finish each assembly. Also included are 54 pairs of solid male and female size-20 terminals sized for 20–22 AWG wiring and a plastic terminal removal tool for safe disassembly.

• PA66 nylon DTM housings: 2/3/4/6/8/12 cavities
• 54 pairs of size-20 male and female solid contacts (20–22 AWG)
• Red sealing plugs for unused cavities
• Wedgelocks and Deutsch plastic removal tool

How do the solid size-20 terminals perform and install?

These terminals are solid (non-stamped) contacts with nickel plating for improved conductivity and corrosion resistance. They are designed to crimp onto 20–22 AWG wire and then insert into the DTM housing for a secure, vibration-resistant connection.

• Nickel-plated surfaces for wear and corrosion resistance
• Solid construction for mechanical stability under vibration
• Compatible with standard single-indent crimp or recommended 4-indent tools
• 54 pairs supplied to cover multi-cavity assemblies

Can I use this kit outdoors or in wet environments?

DTM housings in the kit are molded from PA66 nylon and are designed to mate with sealed contacts and plugs to reduce moisture ingress. The included red sealing plugs let you close unused cavities, and when correctly assembled with sealed contacts they help maintain reliable performance in damp or dirty conditions.

• PA66 nylon bodies resist aging and environmental stress
• Sealing plugs block unused cavities from water and debris
• Properly crimped and seated terminals form a sealed interface

What tools and best practices are recommended for assembly?

While the kit includes a Deutsch-style plastic removal tool for safe terminal extraction, quality crimps require a dedicated crimping tool. JRready recommends using a professional 4-indent crimper for the highest mechanical and electrical integrity; check each crimp visually and electrically before final installation.

• Use a 4-indent crimping tool for consistent crimps
• Confirm terminal seating and wedgelock engagement
• Use the included removal tool to avoid damaging seals when servicing

Who is this kit best suited for? JRready ST6484 is aimed at automotive electricians, motorsport teams, off-road and marine technicians, and well-equipped DIYers who need versatile Deutsch DTM components for repair, prototyping, or custom harness work. It supplies the common cavity counts, solid terminals and service tools to assemble sealed, serviceable DTM connections for engine bays, sensor harnesses, control modules and other applications where a compact, sealed multi-pin connector is required.
