I want to replace the four wires which are split into eight and replace them with four RCA cables coming from the pre-outs on my Kenwood unit.
There are so many wires there it is confusing to these old eyes. Crawling around is also hard on my legs.

Thanks to rereading pizzguys post, I went to the thread he mentioned and figured out the correct plug, top right in the photo, I pulled it out and have cut four RCA cables to an ample length (5’) and I am now exposing the wires in the cable. The connections to the plug wires will be soldered and insulated.
The four cables will be red and yellow for the door speakers and white and black for the subs.

I finished wiring the Kenwood Nav radio and the radio, navigation and reversing camera all seems to work.
