this harness. If it will be used, please refer to the ASWC-1 instructions for radio
connections and programming.

Initializing the GMOS-044

Note: If the radio does not come on within 60 seconds, turn the key to the
off position, disconnect the interface, check all connections, reconnect the
interface, and then try again.

functions of the installation for proper operation, before reassembling the dash.
