Plug and Pins Only – Matching Set of Deutsch DTP-4 Connectors (25 Amp)

High-Power Sealed Connectivity for Demanding Loads

When your electrical demands exceed the limits of standard connectors, the Deutsch DTP-4 Connector Set steps in. Rated for a robust 25 Amps per circuit, the DTP series is the heavy-duty sibling of the ubiquitous DT series. This 4-pin matching set is engineered to handle high-current applications such as high-performance fuel pumps, heavy-duty cooling fans, and motorsport ignition systems without the risk of overheating or voltage drop. This "Plug and Pins Only" kit empowers the fabricator to build custom high-power harnesses with continuous wire runs, eliminating the resistance and potential failure points of spliced pigtails.

Engineering Deep-Dive: Thermal Management and Contact Area

The DTP connector utilizes larger Size 12 contacts, which provide a significantly greater surface area for current transfer compared to the standard Size 16 DT contacts. This increased mass reduces contact resistance, minimizing heat generation under high continuous loads. The thermoplastic housing is larger to accommodate these contacts and provide enhanced dielectric isolation. Like the standard DT, the DTP features an integral latching system and a silicone rear grommet that seals around wire insulation (typically 10-14 AWG), ensuring an IP67 environmental rating. This makes it the only safe choice for high-current devices located in wet or dirty environments, like frame-mounted fuel pumps or off-road lighting.

Operational Benefits: Power Without Compromise

Using the correct connector for the load is critical. Running 20 amps through a standard 13-amp connector will lead to melting housings and potential fire. The DTP-4 ensures you have a safety margin. The stamped and formed contacts included in this kit are designed for a crimped connection that creates a gas-tight bond with the heavy-gauge wire, ensuring that power delivery is consistent and reliable. The vibration-resistant locking mechanism ensures that your critical high-power circuits remain connected even under the harshest race conditions.

Fitment and Application Scope

The DTP-4 is essential for:

• Fuel Systems: Dual or high-flow fuel pump wiring (e.g., Walbro 450, Bosch 044).
• Cooling: High-CFM radiator fans and intercooler pumps.
• Ignition: Main power feeds for CDI boxes or multiple high-output coils.
• Lighting: High-wattage off-road light bars.

Technical Specifications

Summary & Includes

The HT-031204 Kit is the heavy-lifter of the connector world. When you need to move serious amps in a sealed package, accept no substitutes.

Includes:

• 1 x DTP04-4P Connector (Receptacle)
• 1 x DTP06-4S Connector (Plug)
• 2 x Wedge Locks (Orange)
• 8 x Stamped & Formed Contacts (Size 12, 4 Male + 4 Female)

Crimping Note: These Size 12 contacts are large. Ensure your crimp tool is rated for 10-14 AWG Deutsch DTP contacts. A standard Size 16 DT crimper is too small and will damage the terminal.
