Answer 2

You dont need to use the original wiring. If it's too confusing, leave it alone and run new wires. All you need to do is run the power for the radio to a switched key power fuse in the fuse box, and the yellow wire from your radio to a fuse thats always powered, thats the memory wire, to remember settings and presets, then the black, (Ground) just need to be connected to some part of the car which is metal.
