The single black and blue wire I believe is the ground but I put my ground wire directly on to the metal (I put it in to one of the screws that were in metal in the back.)

The two brackets should plug into two of the sockets on the wiring harness with a big one on the harness left over.

The harness should have a big plug that isn't used, it's for a different type of stereo I believe.

Then you have to connect the loose wires from the wiring harness to the loose wires on the piece that came with the stereo. Read the instructions on both the harness and the stereo and they will explain which colors go together. You will be better off connecting those wires with some wire crimpers and some connectors, but you can just twist them together and secure it with electrical tape.

did all ^ that above and still having issues had it working for roughly 5 minutes and then went to plug in the AM atenna and now no power nothing works checked fuses doesnt seem to be blown but i do not know its a dual deck i bought the connecter for the stock to new stereo but its not even sending power to the plugs

PLEASE HELP?????
