I suggest that if you want a nice walkthrough and technical support hit up Crutchfield. They're good for that. Send them an e-mail and tell them your car and what you bought to install and that you wanted to purchase the "free installation gear" that they would've sent you if you purchased through them. Not only will you get everything you need to make your life easier (speaker connectors that connect to stock wiring and other things) but you'll get step-by-step install instructions and they even include the phone support with just buying the install gear so you can call them free and get support while you do it every step. I did it for my car cause I've never done a component install. The total for the gear was under $30 for me. Still waiting on my head unit to arrive so I can hook it up. I think this would be an easy way for you to get everything you need at once and have on call support as well so if you encounter a problem you can get help fast rather than posting here and waiting for a response. Crutchfield is expensive for items but their customer support is definitely top notch.
