Not sure if you're still looking for help...but what are you hung up on? Is there any special bypass harness that you need for an install in a Honda (i.e. GM needs a box to bypass the chimes & onstar audio, etc.)? If not, buy a basic wiring harness for your vehicle (available at any car audio store, walmart, ebay, etc) and then splice the wires accordingly.
You can use butt/crimp connectors or solder...whatever you feel like doing. Solder is better, some say, but I've never used anything other than butt connectors and have never has an issue. Typically, I bring the new harness in the house with the new radio, make all possible connections there, and then bring it out to the car and plug it in to make sure it's right before physically installing it.
After that, it's just a matter of doing the DVD/Nav bypass workaround if you so choose...but you might want to make sure everything works the first time around, before you go messing with other important wires in your less-than-confident situation. However, as matlock mentioned, pry out the mute wire by releasing the white tab with a pin or knife point, then plug it in to the appropriate slot.
I would assume the RCA's come in to play if you have a factory or add-on amp...?
