Accessory Power Relay Connector for Dodge and Chrysler

Standard Ignition S-728 is an accessory power relay connector built for electrical repair work on a wide range of Dodge, Chrysler, and Plymouth vehicles. It uses a male connector body with female 4-blade terminals and a 4-wire pigtail assembly to restore a secure relay connection where the original socket has failed.

Standard Ignition S-728 is a practical replacement for damaged, heat-affected, or corroded relay connectors on applications such as Dodge Dakota, Ram 2500, and Chrysler LeBaron. It is engineered with high-grade materials to support strong conductivity and consistent terminal contact in demanding underhood and body electrical circuits.

Key Features

  • Accessory power relay connector for electrical connector repair
  • Male connector with female 4-blade terminals
  • 4-wire pigtail assembly for relay socket replacement
  • Built with materials selected for conductivity and connection integrity
  • Direct replacement style for common Chrysler, Dodge, and Plymouth applications
  • Standard Ignition S-728 cross-references Hygrade Tuneup 584 for the same application

Detailed Description

This Standard Ignition S-728 connector is designed for technicians replacing a failed accessory power relay socket on older Chrysler-family vehicles. It is a fitment-based solution for many 1983-1996 Dodge, Chrysler, and Plymouth models, including Dodge Dakota, Dodge Ram 2500, Dodge Ram 3500, Chrysler Daytona, and Plymouth Voyager. The connector layout and 4-blade terminal design support a secure electrical interface where the original connector has become brittle, loose, or heat damaged.

Standard Ignition builds its pigtails and sockets using high-grade materials and long-running engineering experience focused on solving common OE connector failure points. For repair planning, this part number is S-728 and it also appears under interchange references such as 1P1191 and PT358.

What It Helps Repair

  • Intermittent relay power caused by worn terminal contact
  • Heat damage at the accessory power relay connector
  • Corrosion or oxidation in the relay socket
  • Broken or brittle connector housing on older vehicles
  • Electrical connection loss on Dodge Dakota, Ram 2500, and Chrysler LeBaron applications

Installation Notes and Tips

Verify the connector style, terminal count, and vehicle-specific fitment before installation. Match the existing relay cavity and wire layout to the S-728 pigtail assembly, then transfer or splice the circuit connections according to the vehicle wiring diagram. For best results, inspect nearby terminals, relay blades, and harness condition before completing the repair.

Quality Assurance

Standard Ignition supports this connector with product development focused on technician needs and OE-style electrical repair. The S-728 is built to address common connector failure issues found in original equipment relay sockets and to restore dependable terminal contact in the repaired circuit.
