3.N5 bench cable

This activation enables support for the Delphi 3.N5 bench cable, including all its supported wiring variants (if multiple exist).
To use this activation, you'll need an Express Box along with the C2 Cable (96-58pin connectors) which together provide the physical connection to the ECU.

Each of our cables (C1, C2, ... Cx) can connect to multiple ECUs in both boot and bench mode, depending on the activations.
Thanks to this innovation, full ECU coverage is achieved with just a few physical cables, supporting over 350+ types of control units and their 440+ wiring variants.
This allows you to expand your bench cable coverage with an investment of only 8–39 EUR per ECU, compared to the 80–250 EUR cost of traditional bench cables.

This 3.N5 ECU is implemented across the following vehicle brands. With the Express Cable, you're fully covered:

You can buy the (physical) cables with full activation included - this is the most cost-effective option.
If you'd rather start small and expand later, you have two options: activate ECUs one by one (like this 3.N5), or save more by purchasing a bundle of, say, 10 bench cable activations in advance - and decide later which ECUs you want to activate.

Note: The physical cable, Express Box, and other items shown are not included - they are for demonstration purposes only. This is a software activation for use with an existing Express Cable set.

3.N5 Bench Cable

The Delphi 3.N5 bench cable is fully supported by this wiring layout, ensuring effortless bench-mode connectivity for tuning or repair.

Why choose the Delphi 3.N5 bench cable?

No need to juggle dozens of cables—this unit is part of a smart network that adapts to many ECU types with ease.

Whether you're performing a full ECU reprogramming, adapting immobilizers, or diagnosing bench-level issues, the Delphi 3.N5 bench cable gives you reliable access to critical pins without opening the unit.

The design of this solution prioritizes both compatibility and workshop efficiency. Unlike traditional cables that are limited to one function or ECU model, this bench cable operates within a flexible modular ecosystem — perfect for dynamic environments and frequently changing project needs.

From just a few well-designed cables, you unlock bench access to hundreds of ECUs — no overstocking required.

Unlike generic bench wires, this Express cable is optimized for precision pin contact and shielded for signal integrity during sensitive operations.

Who is this cable for?

This product is an excellent fit for tuning professionals, ECU programmers, remapping engineers, and anyone needing consistent and safe bench access to the 3.N5. Whether you're working with stock vehicles, damaged ECUs, or highly modified setups, the Delphi 3.N5 bench cable enables access without opening or soldering.

Garage workshops, mobile technicians, and electronic service centers will benefit from the speed and convenience this cable offers. It’s a go-to tool for those who value both precision and reliability during bench-mode operations.
