Creating a test bench setup

This article is a draft. It is not finished yet, information contained in it might've not been verified and could change at any moment |
This article won't cover the most basic ECU<>K-Line adapter connection since all information required for that can be found in the ECU pinout pages.
Instead, we will focus on creating a more complete environment that'll reassemble the actual car - allowing you to swap parts, test inter-connected systems such as the immobiliser, and most importantly - research. The purpose of this article is mostly to organize connector part numbers and pinouts in one place so the process is more straightforward for the next person
Ignition switch - key sensor, immobiliser antenna, illumination
Ignition switch connector
Female (harness) side connector: KUM PH772-06015 Female (harness) side terminals: Faston 6.3mm
| Ignition switch pinout. Female side, looking from the front
<tab> | ||
|---|---|---|
| #3. Ignition output | #2. +12v input | #1. Starter output |
| #6. Ignition output | #5. +12v input | #4. Accessory output |
As seen in the diagram below, #3 and #6 power different BCM fuses but they're essentially the same and swapping them won't do any harm
Key sensor, immobiliser antenna, key illumination
