Cummins Valve Cover Conversion Harness – 2006–2007 Valve Cover to 2003–2005 5.9L Engine

This Cummins Valve Cover Conversion Harness is designed to connect a 2006–2007 5.9L Cummins common rail valve cover and internal injector harness to the 2003–2005 engine wiring harness, enabling a clean and direct swap of the updated style valve cover onto early-model 5.9L engines.

The 2006–2007 valve cover features dual oval 6-pin connectors, while the 2003–2005 engines uses three square 4-pin connectors at the injector harness interface. This adapter bridges the gap—no cutting, splicing, or rewiring needed—making it ideal for top-end rebuilds, updated valve cover installs, or replacing cracked early-model valve covers with the more reliable later style.

Key Features:

  • Specifically for 2003–2005 Cummins 5.9L (Dodge Ram 2500/3500) with OEM square 4-pin injector harness plugs
  • Adapts to 2006–2007 valve cover/injector harness with dual 6-pin oval connectors
  • Plug-and-play installation — no tuning or electrical modifications required
  • High-temp automotive-grade wire and OE-spec connectors
  • Heat-shielded and abrasion-resistant loom for engine bay durability

Why Upgrade to the 2006–2007 Valve Cover?

  • Improved injector harness design integrated into the cover
  • More durable plastic construction with better sealing
  • Easier future maintenance and part availability

Compatible With:

  • 2003, 2004, 2004.5, 2005 Dodge Ram 2500/3500 5.9L Cummins
  • 2006–2007 style Cummins valve cover & internal injector harness (OEM or aftermarket)

Note: This harness is only for converting the injector harness connection — it does not affect sensor wiring or ECM tuning.
