Sony-Pioneer Wired DCI-3
The DCI does NOT work like the factory dash controls so review the Operation section before using it. Be careful if you
are doing your own wiring and follow the diagrams below; do not assume “color-to-color” wiring.
Do NOT mount the DCI module behind, below, or above the HU where it can get crushed or overheated. Put it in
an accessible place under the dash so you can change the switch options at a later date.
Important note – Some head units have the wired remote feature disabled from the factory and require changing
an option in the setup menu. If your DCI doesn’t work check your HU manual carefully for this setting.
Installation using the Pioneer Plug-n-Play harness
Insert the black connector of the PnP harness into your head unit,
connect the blue plug into the Honda stereo harness, and then plug DCI
module into the small white connector. The supplied 3.5mm cable goes
into the jack on the DCI and the other end into the “Wired Remote” input
on the head unit. This is usually a 3.5mm jack on the rear panel labelled
“W/R”. NEVER connect the DCI to an AUX or MIC jack.
If you need an “amp turn-on” wire, T-tap the light blue wire with a white
stripe, it’s located next to the red wire in the blue connector.
If you purchased the SCV Wiring Kit with the PnP harness follow the
instructions included in the kit to complete that part of the installation.
Installation without the Plug-n-Play harness
If you have the DCI Adapter Harness your
job just got a lot easier because it’s the
only adapter on the market that includes
the wires for the S2000 dash controls, and
it comes pre-wired for the DCI.
If you have a generic adapter harness you
will have to splice the DCI red and black
wires into the switched power wires for the
head unit, and then splice the DCI green
and purple wires directly into the factory
stereo harness green/red and yellow/blue
wires (as if the DCI Adapter Harness in the above diagram were missing). The DCI Blue wire is optional and is described
in detail below.
Plug one end of the included 3.5mm cable into the jack on the DCI and the other end into the “Wired Remote” input on the
head unit (see your head unit manual to determine the jack location). This is usually labelled “W/R” on Pioneer and
“Remote In” on Sony head units. Some Sony head units have a recessed jack so make sure the plug goes in all the way.
NEVER connect the DCI to an AUX or MIC jack.
Blue wire - Optional Wired Mute connection
- The DCI can perform the mute function one of two ways: either through
the 3.5mm cable that is used for the rest of the commands or via a dedicated Mute or ATT lead on the head unit. If your
head unit has a wire lead for this purpose you should set DCI switch #1 to OFF to utilize that feature. This will usually
pause playback and fully mute the sound, similar to the way the OEM radio operated.
If your head unit does not have a dedicated mute wire then you must set DCI switch #1 to ON, which will send the MUTE
command via the 3.5mm cable. In most cases this will lower the volume but continue to play, as this feature is controlled
by the head unit software and unfortunately can’t be changed to provide the “pause” function.
SCV
- If you purchased the SCV wiring kit refer to the instructions in the kit to install and program the SCV feature.
