How we checked it
- We start from Haltech's pinout table for this ECU.
- We read every pin again from a second Haltech document, the wiring diagram or the quick start guide. A script compares the two, pin by pin.
- A pin is only shown when its function and its wire colour match in both. Where a diagram has no text to read, we read the pins off the drawing itself.
- The notes are Haltech's own words from its pinout table.
