Honda ECM/PCM Connectors

Honda ECM/PCM connectors are now embossed with geometric shape symbols to easily tell them apart. Connector A (white) has a square; connector B (gray) has a triangle; and connector C (green) has a circle.

These shapes are featured on both the ECM/PCM sides and the electrical harness side of the connectors. This currently applies to 2008 and later Accords, 2006 and later Civics, 2009 and later Fits, 2005 and later Odysseys, 2005 and later Pilots and 2006 and later Ridgeline models.
