Buying Electrical Connector Parts for a 2012 Acura TSX

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 2.4L L4 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.

How many electrical connector parts fit the 2012 Acura TSX?

Our catalog currently lists 59 electrical connector parts for the 2012 Acura TSX across 33 subcategories and 12 brands, covering the 2.4L L4 engine. Each part is matched to the engine(s) it fits.

What are the signs of electrical connector problems on a 2012 Acura TSX?

What should I replace at the same time?

Where labor overlaps, use heat-shrink crimp connectors rather than twist-and-tape for any pigtail splice, especially outside the cabin.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2012 Acura TSX was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2012 Acura TSX?
