MS3Pro EVO+ pinout
Every pin of the 35-pin White, 35-pin Gray, and 23-pin Black connectors, with the wire colours of MS3Pro's harness. Tap a pin to see what it does.
Every pin checked against 2 MS3Pro documents- Connector White · 35-pin
- Connector Gray · 35-pin
- Connector Black · 23-pin
MS3Pro's documents list the pins but do not draw the plug, so we do not draw it either.
Pick any pin in the table to see its function and the documents it was checked in.

MS3Pro EVO+ 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.
