1986-1989 Corvette C68 ECC Air Conditioning Bench Test Cable
This bench test power cable is a great way to power up the C68 Electronic Climate Controller AC Controller while it's outside of the car. It's a great way to determine if the problem is with the C68 module or with the car wiring, and to test the repairs you've made.
The cable provides 12V power and ground to the controller. It allows for testing of the basic functions of the AC Unit (backlighting, power supply, display segments, buttons, LEDs, AC Clutch Control, external temperature, heated mirros or back glass, etc). Note that it does not include capability to test programmer module or blend door module or Blower Modules due to connector availability issues.
Update: The bench test cable now includes two resistors connected to emulate the internal and external temp sensors in your car, as well as functionality for testing the AC compressor request output and the external heated mirrors / heated back glass option!
Note: As of 9/2020, the cigarette lighter plug pictured is no longer available. We have removed it from the kit and adjusted the price accordingly.
