Crutchfield told me to use RCA jacks (and that there was no subwoofer output from the headunit) so I taped off the wire speaker outputs. I also taped off dimmer (orange wire) as I did not connect to cigarette lighter on the wiring harness adapter. I also taped off the Mute (brown), Antenna control (blue), and Remote Control (blue/yellow) on the Kenwood wiring harness. So only 4 connections.
