Where this comes from

Only Haltech's own documents. Pin names and notes are written exactly as Haltech writes them.

How we checked it

  • We start from the pinout table in Haltech's quick start guide for this dash.
  • Every pin is read again from Haltech's support article for the dash, which shows the same table as a picture (read by eye).
  • A pin is only shown when both give the same function; where they differ, the page says so. Haltech gives no wire colours for the dash harness, so none are shown.
  • Labels are Haltech's own words; words in brackets are its suggested uses, which can be changed in NSP.

Where Haltech's documents disagree
