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

#1 - key sensor, #2 - immobiliser antenna coupled with ignition illumination, #3 - ignition switch

Key sensor, immobiliser antenna, key illumination

Female (harness) side connector: KET MG651044 / Yazaki 7283-1060

Female (harness) side terminals: ???

Key sensor pinout. Female side, looking from the front <tab>
#2. Immobiliser antenna (BCM-HM 1)			#1. Immobiliser antena (BCM-HM 11)
#6. Ground	#5. Key sensor (BCM-HM 4)	#4. Key sensor (BCM-JM 3)	#3. +12v illumination input (BCM-KM 10)
