A: The green color signifies Keying Code C. It features a unique mechanical polarization (slotting) that allows it to mate only with a matching Code C receptacle (such as DT04-12PC). It will not fit into standard gray (Code A) or black (Code B) housings. This design is critical in complex harnesses to prevent cross-mating errors between different circuits.

A: The EP06 modification provides two major upgrades: First, it includes an integrated End Cap that protects the rear wire seals from physical damage and debris. Second, it features Enhanced Seal Retention, which utilizes a modified housing structure to lock the perimeter seal in place, preventing it from rolling or displacing during high-force mating cycles.

A: To complete the connection, you will need 12 pieces of Size 16 DEUTSCH terminals (either solid or stamped & formed, rated up to 13A). Additionally, a W12S-P012 (or standard green W12S) wedge lock is required to secure the contacts and maintain the integrity of the Keying Code C alignment. We recommend using nickel-plated or gold-plated contacts for high-vibration automotive environments.
