DIESEL PARTS / WIRING HARNESSES AND CONNECTORS

# FICM & Injector Harness Connectors

Need FICM or injector wiring connectors? Terminal arrangement and harness design matter as much as the connector shape.

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

FICM and injector harness connectors must match the control module and wiring arrangement. Terminal condition can affect diagnosis.

## Identify the correct FICM & Injector Harness Connectors

Provide controller and injector hardware numbers, connector identification and photographs of the damaged terminal area.

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

Confirm the exact terminal or harness assembly before repairing an electrical connection.

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.

## FICM & Injector Harness Connectors: numbers and identification

These parts may be listed as FICM pigtail, injector harness plug, injector connector repair. Confirm the original module number and programming requirements for your engine.

## Ask DCT about FICM & Injector Harness Connectors

Include the injector or nozzle number, engine identification, relevant cylinder observations and any completed injector testing. DCT can confirm current sourcing options for the correctly identified part; only published store listings establish checkout availability.
