6-Pin Deutsch DT Connector – DT04-6P-C017 / DT06-6S-C017 Waterproof Harness

Direct-fit replacement for Deutsch DT series part numbers DT04-6P-C017 (6-pin male plug) and DT06-6S-C017 (6-pin female receptacle), a 1.6mm pitch IP68 waterproof connector set widely used in automotive, marine, motorsport, and heavy-duty equipment harness applications. The C017 anti-mismate coding key prevents incorrect mating with other DT series connectors.

Deutsch DT Naming Convention Decoded

C017 Anti-Mismate Coding – Why It Matters

The C017 suffix indicates a specific anti-mismate coding key colour and position. DT connectors with different C-codes (e.g., C015, C016, C017) cannot be mated with each other, even if the pin count is the same. This prevents accidental cross-connection of different circuits in multi-connector harness assemblies. Always match the C-code when ordering a replacement connector.

Compatible Applications

• Automotive: ECU harness, sensor arrays, body control module connectors
• Marine / boat: Engine harness, navigation electronics, bilge pump control
• Motorsport / aftermarket ECU: Haltech, MoTeC, Link, AEM ECU harness connectors
• Heavy equipment: Agricultural machinery, construction equipment harness

Diagnosis – DT Connector Faults

• Connector won't mate: Check C-code – mismatched coding keys prevent mating; also check for bent Size 16 contacts in the male plug
• Intermittent signal after vibration: Inspect wedge lock (W6S) – a missing or improperly seated wedge lock allows terminal back-out under vibration
• Terminal removal: Use Deutsch removal tool 0411-240-1605 – never use a screwdriver, which will damage the terminal retention lance

FAQ

Q: Can DT04-6P-C017 mate with DT06-6S-C015?
A: No – C017 and C015 are different anti-mismate coding keys and cannot be mated. Always match the C-code on both sides of the connector pair.

Q: What is the wedge lock for on Deutsch DT connectors?
A: The wedge lock (W6S for 6-pin) is a secondary terminal retention device that locks all terminals in place after insertion, preventing back-out under vibration. It must be fully seated for the connector to meet IP68 rating.
