MS3Pro Mini pinout sheet
A printable sheet with every pin, made from the checked data on this page.
Where this comes from
Only MS3Pro's own documents. Pin names and notes are written exactly as MS3Pro writes them.
MS3Pro user manual (AMP EFI): connector pinout tables
MS3Pro wiring pinout card (AMP EFI)
How we checked it
- We start from the connector pinout tables in AMP EFI's user manual for this ECU: pin, function, wire colour and stripe.
- Every pin is read again from AMP EFI's wiring pinout card for the same ECU (a picture: read by OCR, and by eye where OCR could not read a row). A script compares them pin by pin.
- A pin is only shown when both give the same function. A wire colour is shown only when both give the same colour and stripe; where they differ, the page says so and shows no colour.
- Labels are the manual's own words.
