Overview: The PAC SWI-CAN Steering Wheel Radio Control
Interface is an add-on module for use with the PAC SWI-RC steering wheel control
sold separately) when installing a compatible aftermarket radio into select
vehicles that feature steering wheel controls. It allows you to keep steering
wheel controls that use a dual wire CAN bus to control the factory radio. The
SWI-CAN interprets and converts steering wheel control data to signals the SWIC adapter, allowing you to replace your factory stereo
with an aftermarket deck and continue to use your factory steering wheel
Rotary Switch: The SWI-CAN interface has a
rotary switch that needs to be adjusted to match the vehicle it is being
installed in. The rotary switch has settings from 0 to 9.
Connections: The SWI-CAN interface has an attached 3"
eleven-pin harness that plugs into the optional steering wheel adapter (SWI-RC) which is sold
separately. The interface also contains a female 11-pin connector on the other
side of the interface that the supplied detachable 7" harness, using the 11-pin
male connector end, plugs into. On the other end of this same harness is a 6-pin
plug that plugs into an optional C2R interface (sold separately) which
attaches to the vehicle's factory harness. If you do not use the optional
C2R interface you can also hardwire this connection to your vehicle's factory
Note: There are 6
bare-tinned wire leads coming out of the detachable 11-pin harness that are
not used. There is a sticker wrapped around these wires stating - "These
Wires Not Used For Steering Wheel Interface!"
Wiring Advisory: You'll usually
have to hardwire this adapter into your vehicle's wiring. In most vehicles,
the factory radio plug does not have a wire dedicated to the steering wheel
audio controls, so splicing & soldering is often required. PAC does
provide custom wiring instructions for all confirmed compatible vehicles on
