DIESEL PARTS / WIRING HARNESSES AND CONNECTORS

# Diesel Sensor Connector Pigtails

Need a diesel sensor connector or wiring pigtail? Match terminal layout, seals and keying—not just connector appearance.

Send the original connector or harness number, equipment model and a clear photo when possible. Details such as terminals and seals matter.

## Connector and circuit details

Connector pigtails require matching terminals, keying and seals. The same outer shape may not mean the same circuit connection.

## Match the Right Part to Your Equipment

Identify the sensor or switch part number, pin count, connector shape and wire positions.

Include connector-face and wire-side photos, the number of pins, the length of the repair section and any readable OEM markings. Avoid installing a visually similar but differently wired connector.

## Harness and connector replacement questions

Check weather sealing and appropriate wire repair methods rather than matching on color alone.

Confirm whether the request is for a complete harness, pigtail or a connector-only repair. The mating terminal, seal, harness routing and wire arrangement must be checked against the original.

## Part Names and Identification

Related part names include ICP pigtail, EOP switch pigtail, valve cover connector. Confirm the original number, connector and circuit before ordering.
