You need to separate the red and black wires and confirm that you have constant 12v on the yellow wire and switched 12v on the red wire. If you don't have this, you need to check for obvious problems like bad connections and blown fuses. If there is a blown fuse, do NOT install one rated for greater current than what is recommended on the fuse holder/location in the fuse box.

Well I just finished I had the two yellow constants matching instead and the two red switched and nothing was working so I put both constant and switched together and the dome light and the source light lit up on the radio but it still won't respond

Do you have power on the red and yellow wires where they enter the back of the head unit?
