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.
