Custom X-PROG3 DL501 ECU 16Pin to HDB25 Adapter Cable
2 month ago
Product details
Shenzhen Fubang Wiring Harness Co., Ltd. focuses on manufacturing precision adapter harnesses for automotive ECU servicing, key programming and vehicle diagnostic tooling. With years of experience in custom connector development and strict production quality control, we support locksmiths, auto repair shops and diagnostic equipment distributors worldwide. We engineer custom electrical connectors to match specific vehicle ECU interfaces and programming tool platforms, and our catalog includes professional OBD diagnostic cable for everyday vehicle scanning as well as a comprehensive selection of automotive wiring harness connectors for immobilizer and ECU service applications. Every assembly is built with RoHS compliant materials and verified through full electrical testing.
The X-PROG3 DL501 adapter is engineered as a dedicated interface bridge between the X-PROG3 programming unit and vehicle ECUs equipped with the 16Pin circular connector. Rather than a general-purpose extension wire, this adapter is built specifically for bench and in-vehicle ECU programming tasks where signal integrity directly affects programming success. The HDB25 D-Sub female end plugs directly into the X-PROG3 host, while the 16Pin circular ECU female end connects to the target ECU, providing a clean, direct signal path without intermediate adapters that could introduce connection instability. At just 200mm in length, the cable stays compact and manageable during close-quarters bench work, reducing the risk of accidental pulls or signal disruption mid-programming.

Inside the jacket, five color-coded 24AWG conductors carry power, ground and data signals between the two interfaces, with each wire color corresponding to a defined pin function for easy troubleshooting and verification. The 16Pin circular connector uses genuine AMP crimp terminals and includes a threaded waterproof nut for a secure, vibration-resistant connection, while the HDB25 end features nickel-plated contacts for consistent conductivity over repeated plug cycles. A durable overmolded strain relief at each connector exit protects the internal conductors from fatigue, and the cable body carries a printed DL501XX identification label so technicians can quickly grab the correct adapter from a mixed tool set.
Quality is verified at every stage: each unit passes 100% continuity testing, DC 500V withstand voltage check, insulation resistance measurement and conduction resistance screening before it leaves the factory. Insulation resistance is held above 5MΩ and conduction resistance is capped at 3Ω, ensuring the clean, low-resistance signal path that ECU programming demands. Connectors are visually inspected for cracks, deformation and surface defects, and all materials meet RoHS compliance standards. The finished adapters are individually bagged to prevent scratching and tangling during storage and shipping.
This DL501 adapter is commonly used by auto locksmiths, ECU repair technicians and professional garages for ECU read/write operations, immobilizer module servicing, key matching, bench ECU testing and X-PROG3 tool integration. It is a practical addition to any professional automotive programming toolkit. For projects requiring different ECU connector styles, alternate pin mappings or custom labeling, we can modify the design using our custom electrical connectors capability to create a dedicated adapter for your target vehicle or tool. We continue to expand and refine our automotive wiring harness connectors range, and our OBD diagnostic cable products can be combined with these adapters to build a complete vehicle service wiring kit. Feel free to share your ECU interface specifications or tool requirements for sample development and pricing.
