Attention! This interface will work with models that are either non-amplified, analog amplified,
or digital amplified. Please follow the instructions carefully for your model vehicle. Failure to
do so will result in either no sound, or low sound. If you are unsure if your vehicle is factory
amplified or not, please contact your local dealership.
For models with an analog amplifier:
From the 16-pin harness with stripped leads to the aftermarket radio (harness included with interface):

hear sound from the factory amplifier.
