Connections to be made
From the 3308 harness to the aftermarket radio:
• Connect the Black wire to the ground wire.
• Connect the Yellow wire to the battery wire.
• Connect the Green wire to the left rear positive speaker output.
• Connect the Green/Black wire to the left rear negative speaker output.
• Connect the Purple wire to the right rear positive speaker output.
• Connect the Purple/Black wire to the right rear negative speaker output.
• If retaining the factory AUX-IN jack, connect the Red & White RCA jacks
to the AUX input.
Note:
a. The AUX-IN jack can only be used if it is a single AUX-IN jack.
b. If the AUX-IN jack has a USB port, neither can be used.
12-pin pre-wired ASWC-1 harness:
• This harness is to be used along with the optional 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, please refer to the ASWC-1 instructions for radio
connections and programming.
Note: Disregard the harness that comes with the ASWC-1.
• Connect the Red wire to the accessory wire.
Note: The relay attached to the 3308 harness is only for audible turn signal
clicks. No extra steps are required to retain this, so leave it as-is.

With the key in the off position:
1. Connect the 16-pin harness with stripped leads, and the 3308 harness,
into the interface.
2. Connect the 3308 harness to the vehicle.
Note: Make sure to connect the factory LDVS harness (blue connector)
that was disconnected from factory radio, into the interface.
3. Locate the factory antenna connector in the dash and complete all necessary
connections to the radio. Metra recommends using the proper mating adapter
from Metra.
4. Before using the kit it must be initialized.
Attention! If the interface loses power for any reason, the following steps will
need to be performed again. Also, if installing an ASWC-1 connect it after you
initialize and test the interface/radio, with the key in the off position.
a. Turn the key (or push-to-start button) to the ignition position and wait until
the radio comes on.
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.
b. Turn the key to the off position, and then to the accessory position. Test all
functions of the installation for proper operation, before reassembling the dash
5. Test the radio and climate controls for proper operation.
