Radio wiring info, Going back to the Oem radio.. No connector. Options

[dudeofchaos]

I had a horrible aftermarket radio that was in the car when I bough it. I just bought an oem radio to replace it because it sucked and was fugly.
Now I can't get it to work because I don't see any oem plug that goes in the oem radio.

There are 2 blue connectors that usually plug in the amplifier, though there is no amplifier (Weird as I thought it wouldv'e came in standard on a Gt-Four.. Or maybe the previous owner removed it? Idk...)
The bigger connector was linked to an adapter to go directly in the aftermarket radio.

My question is do I have to get an amplifier to make it work since there are the 2 blue connectors? Also, I guess I have to find myself an oem connector to plug in the radio, but were should I wire the oem connector when I get it?
(Sorry, I'm kind of a noob with everything electric.)

Thanks for any advice.

I think I still have both the amp and the harness if you can't source any locally.
