UnwiredTools™ ACCII Upgrade Kit



Easy installation and excellent temperature regulation! The UnwiredTools™ ACCII Upgrade Kit replaces the unreliable OEM analog and mechanical climate control system with modern digital microprocessor technology. This upgrade replaces both the OEM Servo and Servo Amplifier.

The latest version of our popular climate control system eliminates the need to splice wires, calibrate the temperature wheel and feed temperature probes under the dash. It even offers higher precision temperature regulation than ever before!

Like all UnwiredTools Automotive products, a One Year Limited Warranty is included.
