Hi,
I'm looking at the diagram you posted and the radio you list (DNR476S). The ADS-RR(SR)-TOY01-DS-IG-EN guide is what we need and can be found when you flash the module or
here. This will allow full functionality of your radio allowing RR to do steering wheel controls, gauges, etc. as applicable in your vehicle. The guide you have, if you look at the center bottom of the page is a -AS-IG-EN version, which won't work with your radio.
Using the -DS guide, you'll notice the area you have labeled "Connected?" is replaced by a single black data cable and a 3.5mm audio jack cable from the RR to the back of your Kenwood radio. Plug the 4 pin data cable into both radio and RR. The 3.5mm cable goes into the Kenwood aux in and other end to the RR.
The dot vs no dot part is indicating where two wires are simply connected together, like would happen between the Kenwood harness and the RR harness. If we aren't showing where that connection is made, there's no dot and you would want to refer to the wire charts on the following pages to identify and test/make those connections.
Let us know if you have any further questions!
