What are these two radio plugs?

Hi gang. I'm installing the radio and backup cam I got my dad for Xmas in his 07 prerunner. There's two extra plugs that came out of the factory radio, that I don't know what to do with, because my harness lot only came with two plugs. I'm hoping I can just ignore the the other two plugs. Please help!

 

the two plugs you already have are for the core functionality. 4 speakers, battery+, key/ignition+, and ground. illumination dimming(orange) and amp turn-on(blue, or blue/white) are optional(illumination dimming has never worked for me, and the amp wire is only for factory power antenna's, or aftermarket amps, which neither are likely to exist in this case).

the other harnesses are either for factory vehicle communication with the oem radio, or similar. the larger unused plug i believe also has the steering wheel control wires in it if equipped, but you need a separate conversion module to interpret the signals for the new radio for that.
