DHD 700-97327685 Updated Duramax CP3 Regulator Jumper Harness 2001-2010 LB7 LLY LBZ LMM 97378671

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. Our 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
• NOTE: Some LB7 trucks are not equipped with this harness. Please verify your truck requires this harness prior to purchasing.
