Installation Steps
1. Remove the factory radio.
2. Make all connections between the aftermarket radio’s harness and the supplied vehicle harness, as described in the wiring
connections chart on page 1.
3. Be sure to connect the Blue / White wire even if the vehicle is not equipped with an amplier.
4. Connect the C2R-CHY4 harness to the vehicle’s harness.
5. If retaining SWC, then follow the steps in the next section “SWC Output Connector”
SWC Output Connector
1. The harness has a SWC output connector. For ease of installation,
all necessary connections for an SWI have been made for you. Both
loops should remain intact.
2. When using this SWC output connector with the SWI-RC, the SWC
interface must be programmed for version 2 (refer to SWC interface
programming instructions for exact programming sequence and
button assignment order).
3. When using this SWC output connector with an SWI-CP2, you can
either program the SWC interface with a PC, or set the DIP switches
according to the PC app.
