Dirty Hooker Diesel 01-10 GM 6.6L Duramax DHD Updated CP3 Regulator Jumper Harness

This harness connects to the fuel pressure regulator on the CP3 and the engine harness. These harnesses are subject to extreme heat and are often targets for rodents.

DHD always recommends replacing this complete harness section rather then doing wire repairs. High resistance repairs could lead to idle fluctuations and erratic engine rpm.

DHD's updated regulator jumper is designed to replace your flimsy OE jumper. DHD's jumper features a full split loom sleeve, larger gauge primary wiring and foil shielding to prevent interference. Best of all, this is a seamless harness leaving no room for connector failure or corrosion.

Features:

  • Direct Plug and Play Replacement
  • More Durable Construction
  • Larger Primary Wiring
  • Foil Shielding to Prevent Interference
  • Expanded Model Coverage Over OE

Fitment:

  • 2001-2010 Duramax LB7 LLY LBZ LMM 6.6L
