How does this kit protect the fuel pump and electrical system?

The relay wiring kit routes higher, steadier voltage to the fuel pump through a dedicated relay and wiring harness, reducing voltage drop and heat in existing factory wiring. That reduces electrical load on sensitive modules and minimizes the risk of relay failure from prolonged high-current draw.

• Dedicated relay for cleaner power delivery to the pump
• Wiring sized to reduce voltage drop under heavy load
• Integrated protection features to avoid overloads
• Pre-terminated connectors preserve OEM harness integrity

What parts and part numbers does it replace?

This JUNRUO kit serves as a replacement for several common relay and wiring assemblies used in Mopar vehicles, matching the electrical function and connector types of the originals. Use the listed numbers to verify cross-compatibility with your vehicle’s service manual or parts diagram.

• Replaces part numbers: 68269523AD, 04727370AA, 4727370AA
• Also cross-references: CBWPR091AA, CSZDV621AA, CBP4P541AB
• Engineered to meet the electrical specifications of the original assemblies

Is installation difficult and what tools are required?

The kit is designed for plug-and-play replacement so no major wiring modifications are necessary. Typical installation requires basic hand tools, access to the pump relay area, and a few minutes to seat the connectors and secure the relay mounting point.

• Plug-and-play connectors match factory harnesses
