2019 Ram 3500 Electrical Parts: OEM & Replacement (158 Parts)

Q: How many electrical parts fit the 2019 Ram 3500?

Our catalog currently lists 158 electrical parts for the 2019 Ram 3500 across 26 subcategories and 27 brands, covering both the 6.4L V8 and the 6.7L L6 DIESEL Turbocharged. Each part is matched to the engine(s) it fits.

Q: Do electrical parts differ between 2019 Ram 3500 engines?

Some do. 69 parts fit every engine; the other 89 are engine-specific. Each row (and the filter at the top) shows which. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.

Q: What are the signs of electrical problems on a 2019 Ram 3500?

Common symptoms include slow cranking on cold mornings, a battery light that flickers, dim lights at idle, or a check-engine code pointing at a sensor circuit. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

Q: What should I replace at the same time?

Where labor overlaps, clean or renew the battery terminals and grounds with any charging-system repair.

Q: 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 2019 Ram 3500 was originally sold in the US, the safest choice is a part marked for the US market.

Q: How do I make sure a part fits my 2019 Ram 3500?

First match the engine — each row shows which engine(s) the part fits. Then test before replacing — a failed alternator and a bad ground can look identical, and sensors are frequently condemned for wiring faults. The notes column carries position and trim qualifiers where they apply.

158 Electrical parts are listed for the 2019 Ram 3500, in 26 part types, covering both the 6.4L V8 and the 6.7L L6 DIESEL Turbocharged. Each one has a brand, a manufacturer part number and notes that say where it fits.

On the 2019 Ram 3500, the electrical system covers charging, starting and the sensors and modules the vehicle relies on, from alternator and starter to oxygen sensors. Most of the listed parts are Alternator / Generator (54 parts), Horn (14 parts) and Starter Motor (13 parts). The other 23 part types cover the remaining 77 parts.

This table covers the alternators that charge the battery and run the electrical load. Typical signs include dim lights at idle, a battery lamp, or a growl from the charging pulley. Load-test the battery and inspect the belt and grounds — a bad ground mimics a failed alternator.

Buying Electrical Parts for a 2019 Ram 3500

On this vehicle, the electrical system covers charging, starting and the sensors and modules the vehicle relies on, from alternator and starter to oxygen sensors.

Match the engine first. Some electrical parts fit every engine; others are 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, clean or renew the battery terminals and grounds with any charging-system repair.
Cross-reference the manufacturer part number against your old part or a service-manual listing.

Start with the largest groups on this page: Alternator / Generator and Horn .

Frequently Asked Questions

How many electrical parts fit the 2019 Ram 3500?

Our catalog currently lists 158 electrical parts for the 2019 Ram 3500 across 26 subcategories and 27 brands, covering both the 6.4L V8 and the 6.7L L6 DIESEL Turbocharged. Each part is matched to the engine(s) it fits.

Do electrical parts differ between 2019 Ram 3500 engines?

Some do. 69 parts fit every engine; the other 89 are engine-specific. Each row (and the filter at the top) shows which. 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 problems on a 2019 Ram 3500?

Common symptoms include slow cranking on cold mornings, a battery light that flickers, dim lights at idle, or a check-engine code pointing at a sensor circuit. 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, clean or renew the battery terminals and grounds with any charging-system repair.

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 2019 Ram 3500 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 2019 Ram 3500?

First match the engine — each row shows which engine(s) the part fits. Then test before replacing — a failed alternator and a bad ground can look identical, and sensors are frequently condemned for wiring faults. The notes column carries position and trim qualifiers where they apply.
