In an effort to simplify the design of new boards, this page is a reference of known ECU connector part numbers. Many times these can be difficult to find and are closely guarded by many wiring specialists who have significant price markups without supplying the manufacturer part numbers etc.
These part numbers are primarily for the ECU side. Where known, a loom side part number is also shown.
