Why did u cut up your wires? Wire it back like it was and get the correct harness. Otherwise you will have to get a diagram for your car.

I do have a diagram for it but i still dont understand what some of the wires mean! it says it has two 12V wires? what the heck does that mean!

[accuab]

One 12 v is a constant. It means it is on all the time. This is used for the internal memory of the head unit. The other is a 12 v accessory which will only be on when you turn the key on. If you're not sure which of the factory wires is which, connect a multimeter to one and ground it with the key off and see if it has power. One of them should have power with the key off.

So the one that has power constantly will be the one i connect to the red (accessory) wire??

Read the label on the yellow wire and maybe you'll have hope.

on the new harness...

yellow is constant 12v +
Red is switched/acessory 12v+
black is 12v-
