Compatible with all of our head unit and DCI wiring harnesses except the Joying DCI. This kit allows you to easily make the connection to the vehicle speed signal so you can use the "Speed-Controlled Volume" feature that is built into every DCI. The wire supplied in this kit is pre-terminated so it slides into the empty slot in the DCI Harness connector. The other end connects to the speed signal wire using the provided Posi-Tap connector. No special tools needed.
To install this kit you will need to remove the passenger dash access panel (AP1) or the passenger dash shelf (AP2), which requires some hand tools and is described in the included full-color installation manual. It's not a difficult job but if you're not experienced with auto interior work we suggest you preview the instructions before buying.
