Buying Electrical Connector Parts for a 2017 Cadillac XTS
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.

Frequently Asked Questions
How many electrical connector parts fit the 2017 Cadillac XTS?
Our catalog currently lists 69 electrical connector parts for the 2017 Cadillac XTS across 33 subcategories and 11 brands, covering both the 3.6L V6 and the 3.6L V6 Turbocharged. Each part is matched to the engine(s) it fits.
Do electrical connector parts differ between 2017 Cadillac XTS 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 2017 Cadillac XTS?
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 2017 Cadillac XTS 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 2017 Cadillac XTS?
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.
