I tried using this, but got confused when it said to use the same wire for two different things. I hooked it all up anyways, and it didn't work. Still, thanks for trying to help.
It isn't telling you to use the same wire for two different things. It is telling you what wires correspond with which wiring.
You would match up the 12V constant for the factory to the 12V constant for the aftermarket unit....and so on.....
Example.....
Car Radio Battery Constant 12v+ Wire: Orange TO Yellow 12V Constant / Memory
1. So First you would wire the Orange from your factory wiring to the Yellow on your aftermarket radio wiring.
You are making this way more difficult than it has to be.
Example Two
2. Car Radio Accessory Switched 12v+ Wire: Yellow TO Red Switch / Accessory
So you would wire the yellow wire from your factory wiring to the Red "ignition/Switched 12V" on your aftermarket Head Unit Wiring.
If that doesn't make sense I really don't know how else to explain this to you
I can even see in the picture you posted that the colors seem to be correct.
Also make sure your vehicle is off and if things dont work when you turn the car on try hitting the power button on the radio or checking your ACC fuse for the car.
