Buying Electrical Connector Parts for a 2013 Ram 4500

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 6.7L L6 DIESEL 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.

Start with the largest groups on this page: Trailer Connector and Fog / Driving Lamp Connector .

Frequently Asked Questions

How many electrical connector parts fit the 2013 Ram 4500?

Our catalog currently lists 134 electrical connector parts for the 2013 Ram 4500 across 52 subcategories and 16 brands, covering the 6.7L L6 DIESEL Turbocharged engine. Each part is matched to the engine(s) it fits.

What are the signs of electrical connector problems on a 2013 Ram 4500?

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 2013 Ram 4500 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 2013 Ram 4500?

Every part on this page is matched to the 6.7L L6 DIESEL Turbocharged engine. 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.
