Buying Electrical Connector Parts for a 2026 Buick Envision

On this vehicle, the connector system supplies the pigtails and connector bodies that terminate the vehicle harness at lamps, sensors and modules.

Confirm you have the 2.0L L4 Turbocharged engine — every part on this page is matched to it.
Read the notes on each row for position, trim and spec qualifiers before you order.
Where labor overlaps, use heat-shrink crimp connectors rather than twist-and-tape for any pigtail splice, especially outside the cabin.
Cross-reference the manufacturer part number against your old part or a service-manual listing.
