*Sigh* It's a PDF manual, and the instructions and diagrams in it seriously SUCK. The instructions are lacking to the point it's annoying. I also think I'm just going to get this done at a shop. I've heard Autozone electronics suck, and I won't get any kind of warranty if, say, I buy from autozone and the piece goes out in thirty days. With a local shop I get a year warranty on the thing. Yeah, it'll cost more, and yes, it goes against me trying to do everything myself, I just don't want to risk any faulty electrical pieces... It would cost more if the part goes out and I gotta get ANOTHER one... so.. I'm just getting this done at a shop.
