New cd player

I got a new cd player for my car but something is not right. Theres 8 wires coming from the speckers(dashboard) with the intiner cable. My radio has 8 wires for the speckers but there are 3 wires left. And they ARE THE POWER WIRES!!!!!!!!!!!!!! I need some help people. Come on now, we are corolla men and women, Let us come toghter and help each other with things like this. I think there is only 2 wires left after hooking all the specker wires toghter.(from dash) There is a red yellow and black wire, they are the power wires. (on radio) I dont know what to do!!!

The red wire needs power from your battery, the black wire is nearly always the ground wire and the other one is probably the accessory wire to turn it on. :)

just get a wiring harness from your local automotive electronics store for your year corolla
