If you have the instructions to your after market HU, there is a wiring diagram that says which wires are which, disconnect the rear speaker wires from the harness and run wires from them to the new speakers.

 

If I remember right I think mine were a green set of wires from the aftermarket unit. It should say like dig says on the packaging

 

Car Radio Battery Constant 12v+ Wire: Orange
Car Radio Accessory Switched 12v+ Wire: The radio harness does not provide a switched power source. The accessory turn-on is controlled by the lan serial network. Run a wire to the fuse box or ignition switch harness.

Car Stereo Dimmer Wire: N/A
Car Stereo Antenna Trigger Wire: N/A
