Thought that you had not seen it inside the wiring kit as it's all bundled together. The one thing that I think you will need, that's not on your list is connectors for the speakers etc. This is what I am referring to:
I got that one and all the little bits came in handy for wiring. Also, electrical tape (at least 2 rolls), a pair of wire strippers and crimper will be very helpful during the wiring process if you don't have it already in your toolbox. And a small roller for when you are installing the Silent coat down the line. You can borrow all of these from me anytime you want
As I remember more bits and pieces, I will write them down here.
