How we checked it
- Link publishes one pinout document for each ECU: its quick start guide. Every pin here comes from that guide. Link's full wiring manual is only inside its PCLink software, so it is not used.
- A script reads every pin from the guide. Each pin is then read a second time: from Link's guide for a sister ECU that shows the same pin, from the I/O table in the same guide, or by eye from the same guide.
- A pin is only shown when both readings agree on its function and, where Link gives one, its wire colour. Pin numbers are the ones Link prints in its guides.
- Labels, notes and wire colours are written exactly as Link writes them, for example Brown/Orange.
