How do you disconnect a Clifford auto immobilizer on a 99 Hyundai Sonata?

Answer by  ross1976 (196)

Be prepared for the alarms to scream unless you know exactly what you are doing. Switch off the immobilizer or disconnect the power supply before you start working on your Hyundai Immobilizer. Trace the right wires and switches and systematically remove them. All the best!

It would have helped if you paid attention when they installed the Clifford Auto Immobilizer. It's usually a reverse of the steps they did when they fixed it on your 99 Hyundai. Does your immobilizer manual have a circuit diagram that you can decipher - may help!
