DCT PARTS / LINE CARD GUIDE
Diesel Wiring Harnesses & Connectors
Identify injector harnesses, FICM connectors, valve cover pass-throughs and sensor pigtails by exact wiring configuration.
Find the component family before choosing a part
Identify injector harnesses, FICM connectors, valve cover pass-throughs and sensor pigtails by exact wiring configuration. An exact part number and the engine or equipment application determine what can be reviewed. A brand or product family appearing in the line card does not confirm every individual variant is in stock or suitable for repair.
Diesel Sensor Connector Pigtails
Connector pigtails are repair components for damaged wiring terminations. Different sensor plugs may have similar shells but different keying or terminal layouts.
FICM & Injector Harness Connectors
FICM and injector connectors link electronic control hardware to the injector circuit. Connector resistance or damage can complicate diagnosis.
Valve Cover Harness Connectors
Some engine designs route injector wiring through valve cover connections or gasket-associated pass-throughs. Replacing a similar-looking connector can create sealing problems.
How to request an accurate component quote
Send your original part number, any supersession or cross-reference information, the engine and equipment details, and whether you prefer new, rebuilt, refurbished or exchange where actually offered. DCT will confirm applicable fitment, stock, shipping, return/core and warranty conditions for an actual item.
Use the component identification inquiry for unlisted items, or explore the DCT online store for products deliberately made available for direct purchase. Service components must not be shipped until DCT confirms acceptance and receiving instructions.
