CONNECTIONS
12-pin pre-wired ASWC-1 harness:
• This harness is to be used along with the ASWC-1 (not included) to retain steering wheel
audio controls. If the ASWC-1 is not being used, disregard this harness. If it will be used, refer
to the ASWC-1 instructions for radio connections and programming. Disregard the harness
that comes with the ASWC-1.
• Connect the Red wire to the accessory wire.
Note: The relay attached to the GMOS-044 is only for audible turn signal clicks. No extra steps are
required to retain this, so leave it as-is.
