Upgrade an older truck's 4WD engagement with the Dorman - OE Solutions 4WD Actuator Wiring Harness, part number 600-600. It is designed for use when you swap the thermal-style axle actuator for an electric one, for easier engagement and improved operation. It fits many vehicles, among them the 1988-1996 Chevrolet K1500, 1995-1996 Chevrolet Tahoe and 1992-1996 GMC Yukon. See the Buyer's Guide tab for the full list of applications.
Older 4WD systems that use a thermal-style actuator can be converted to newer electric actuator technology. This harness provides the wiring connection that conversion requires, so the electric actuator can take the place of the thermal unit.
- Upgraded replacement: lets you convert an older model vehicle to a new electric actuator.
- Improves operation: uses on-demand actuator technology, and the conversion is designed to make 4WD engagement easier.
- Durable construction: built for reliable longevity and free of defects in materials and workmanship.
- Trustworthy quality: supported by a team of designers and engineers in the United States.
If you are having 4WD engagement problems, diagnose the cause before replacing parts. When you convert to an electric actuator, install this harness as part of that job and follow the vehicle service information for routing and connections.
