This custom-made adapter harness mates with the OEM harness so you can connect your new head unit into the car's factory wiring without damaging or altering the OEM wiring or connector. This is the only adapter on the market that has the extra wires for the S2000 Dash Controls, which are pre-wired to a DCI connector to make it was easy as possible to install your after-market head unit. Use this adapter if you are using a Sony, JVC, or Clarion head unit. For Pioneer, Alpine and Kenwood we have a Plug-n-Play harness that allows head unit installation with no wire splicing.
If you intend to use the Speed-conrolled Volume feature of the DCI you will need to purchase the SCV wiring kit on the Related Products tab.
Installation Hint - make the wire splices from the adapter to your head unit harness outside the car where it's easier to work, such as on a table or workbench. This is much easier than splicing wires inside the tiny radio console.
Modifry Adapter Harness - No instructions needed as all the wires are labelled.
