XRS-9000 Installation & Harness Integration Guide

To ensure a transparent Man-in-the-Middle (MitM) connection, the XRS-9000 must be integrated into the vehicle's High-Speed CAN (HS-CAN) backbone.

1. Locating the Gateway Module (GWM)

Most modern vehicles (2020+) utilize a Central Gateway to firewall the OBD-II port from the PCM. For the V-GLITCH and ROM-SHRED exploits to work, the XRS-9000 must be installed downstream of the Gateway.

2. Pinout Configuration

The following pinout is standard for the AL-11B-CTX interfacing with Bosch and Delphi ECU architectures:

Pin Function Color Code Notes
14 CAN-H (In) White/Blue From Vehicle Loom
15 CAN-L (In) White From Vehicle Loom
01 V-BATT Red Constant 12.6V - 14.4V
37 GND Black Chassis Ground (Shielded)

3. Signal Shielding Requirements

Because the XRS-9000 operates at 480MHz, electromagnetic interference (EMI) can cause packet drops on the CAN-FD line.

  • Use Twisted Pair cabling for all CAN lines.
  • Ensure the drain wire is grounded at the XRS-9000 side ONLY to prevent ground loops.
  • Keep the V-GLITCH trigger wire as short as possible to maintain pulse integrity.
