Description
Description
Fix a common Duramax failure point with this Fuel Injector Connector Pigtail Kit. This replacement connector with a 4.5" pigtail is prone to increased resistance over time — a frequent cause of injector DTCs — and gets your truck back on the road quickly. Typically replaced during injector service, it's a smart preventive fix any time the injectors are out.
Why Choose This Injector Connector Pigtail Kit?
- Fixes a Known Failure Point – Replaces the injector connector that develops increased resistance over time and can trigger injector trouble codes (P0201–P0208).
- Ready to Install – 4.5" pigtail with heat-sealable butt-style connectors for a clean, sealed splice.
- Precision-Built In-House – Fully automated wire cutting and terminal crimping for consistent, high-quality connections.
- 4-Pack Value – Includes four pigtails per kit — enough for a full injector service on the V8 platforms or spares on the inline-six.
Kit Includes
- 4 injector connector pigtails (4.5" lead)
- Heat-sealable butt-style connectors
