WTF is that little black square plug on the right???

Aswell i have a gangster plug for this radio. I got it off my buddies 93 leggy turbo before he sold her... Which now he regrets very much.

The wires have only two problems.

One. I have the power antenna "black/green" and the Ant Amp "green/orange" wires not jointed.

Two. I have 9 pin connectors "Acc 12+V" not connected to anything?

My guesses are that the 9 pin thing is a lose because it has no place on the new impreza connector. The power antenna and "ant amp" thing i have NO clue all i know is the pin on the new style connector is 14 and its "green/orange". Should i join them??

If any one can give me some help if you can understand this, would be great.
