Easiest installation ever - this custom Plug-n-Play harness connects into the head unit, the car's stereo harness, and the DCI to simplify installation of a Pioneer head unit and a Wired DCI. Greatly reduces installation time and there are no worries about making the right wire connections.
If you want to make use of the SCV (Speed Controlled Volume) feature of the DCI you will need to buy the optional SCV wiring kit (SCV Details here). This kit consists of a pre-terminated wire that plugs into the DCI connector, and then the other end is run behind the passenger dash to T-tap the vehicle speed signal. No special tools are needed and all parts and connectors are included. Detailed instructions with photos are included with the SCV Wiring Kit.
Only works on DCIs with a 6-pin connector (2012 or later). Also, may not work on "Stage 4" head units, as the connector appears to be different than "standard" Pioneer models.
