Get a test light. See if the deck is getting power. You should have bought a harness for it, it will be much easier on you. I was going to tell you to take the deck out, and just took up the 2 power wires and ground directly to the battery. Just to make sure that its a working unit.

 

Can't buy a harness, the previous guy cut off the factory harness so all I have left to deal with is a bunch of wires.

 

The alpine harness wasn't properly attaching to the back of hu. Had to keep it together with electrical tape. Thanks for the help WiLL
