Installing oem amp back in., Need help Options

[dudeofchaos]

Alright, so I've decided to put the oem radio and amp in. I have the plug that connects the radio and the amp together. The other plug (the big white one with a full load of pins) that goes in the amp though, where the hell does it go?
I have it in my other celica that I want to swap over, I can't get it out but I wouldn't even know where to plug it. It's disconnected from the amp, but the other end of the plug is still attached somewhere underneath it and I can't get it out.
Any tips on how to remove it and where it goes?

I have an aftermarket head unit but looking at my uncut harness...
There is a bundle of wires running along the top of the dash just above the center console AC vents and clock with a junction box of plugs. A nylon conduit splices off of these wires and runs downwards along the driverside( on my USDM LHD) of the center console cavity. It is ziptied to the dash right behind the ignition key. Right after this conduit passes behind a large metal bracket for the radio mounts, another smaller nylon conduit(about 12 inches long) splits off and terminates into two blue plugs.
