Stereo Question - I Read Other Threads, I read the other threads, I just want to clarify a couple things. Options

Water leak, amp fried, seems pretty standard around here. I read the threads, including the pinned one about the Infinity stereo and I just wanted to get some clarification.

Before I realized that it was the amp, I bought another head unit. I'm planning on bypassing the amp, and I found the bypass harness from the pinned thread. I have a few questions about the best way to do this.

1. I'm assuming that I'm going to do nothing with the black, circular connector on either end, correct?

2. When I hook the bypass harness to the connector under the passenger seat, do I just hook it up and run it back along under the console and up into the dash, or should/can I pull the original wiring back into the dash (if that's where it's coming from) so I don't have that wiring going under my passenger seat? What's the best way to go about this?

3. In addition to the black circular connector, there were two connectors coming out of the stock head unit. One looks like it has 5 wires, one has 4. Do I just leave these unplugged? Do I do anything with these? Do they power anything?

4. Does it sound like I'm completely misunderstanding something?

Thank you very much for the help.
