New stereo wiring harness

Took out my old stereo from my 2010 ext. cab. Here are the harnesses. Trouble is, there were 4 harnesses connected, and I got 2 harness adapters for my new stereo.
What do I do with the 2 other harnesses (the blue one and the black one)

The back of the old stereo with 4 connection spots.

My new stereo, the AVH-P3300BT from Pioneer. The one adapter has an unused colored wire, the orange/black wire.

Any help would be GREATLY appreciated.
Thanks,
Shawn

 

The other two aren't used. Those connectors, I assume, are for factory connections to the satellite radio and steering wheel controls.

 

Thanks! I think you are totally right. I forgot my steering wheel control adapter, so that is one connection. I believe they said my model was pre-wired to take Toyota's XM radio, which I didn't purchase, which would make the other connection.

 

The black connector is the one for the satellite radio hook up, it also is where one would hook up to an OEM radio for a Grom Audio/Dice/others box for iPod/USB/etc.
