Toyota T100 wiring

[ImportBuilder]

My mom has a 1995 Toyota T100 Extended Cab. I pulled the stock HU out of the dash, and looked @ the back of it. the connections are little plugs (I figured it would be like this). I can wire home and computer stereos really well. Hell, I had 2 Xplod subs wired to my freinds home theater system for awhile. and they hit nice n hard, no distortion. anyway, i am competent enough to wire this thing up, but do i need to get a wiring harness adapter when i order my new head unit or what??
in case you cant tell, this is my 1st time doing car audio. i can wire the speakers, i think. they also have the little plugs on them. can Ijust cut the plugs off and wire it like a reg. speaker??

If you want a really easy first time install, go to crutchfield.com and get whatever you choose for head units and components there. They don't have lowest prices, but the amount of free stuff they send with the products kinda makes up for it in the installation. They have plug adapters for every car out there, so you just have to wire the HU up to the adapter and then just plug the adapter into the factory wiring that's there. Same goes for the speakers. They even give instructions (like whole movies) on exactly how to remove speakers from doors, run the wire, basically everything. There's also a lifetime "call us and we'll talk you step by step through anything". I got a couple things there, and now I'm don't basically everything on my own, but it was a great place for a newb to start, IMO.
