Buying Electrical Connector Parts for a 2018 Cadillac CTS

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

Match the engine first. Every electrical connector part here is engine-specific; each row shows which engine(s) it fits.
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.

Start with the largest groups on this page: Engine Wiring Harness / Connector and Body Wiring Harness / Connector .

Frequently Asked Questions

How many electrical connector parts fit the 2018 Cadillac CTS?

Our catalog currently lists 203 electrical connector parts for the 2018 Cadillac CTS across 57 subcategories and 17 brands, covering all 4 engine options (2.0L L4 Turbocharged, 3.6L V6, 3.6L V6 Turbocharged and 6.2L V8 Supercharged). Each part is matched to the engine(s) it fits.

Do electrical connector parts differ between 2018 Cadillac CTS engines?

Yes. Every electrical connector part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.

What are the signs of electrical connector problems on a 2018 Cadillac CTS?

Common symptoms include intermittent faults that move when the harness is wiggled, green corrosion inside a plug, or melted connector housings near heat sources. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

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 2018 Cadillac CTS 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 2018 Cadillac CTS?

First match the engine — each row shows which engine(s) the part fits. Then match the connector by terminal count and keyway, not just appearance — many families look identical but will not lock. The notes column carries position and trim qualifiers where they apply.
