I did the same, but if you cannot use the factory harness you can run the new wire from the where the brown wire hooks up at the fuse block. The incoming wire is white/red, this is power after the ignition. Brown is after the fuse and white/red is before the 15 amp fuse.
I highly recommend that you use the stock harness rather than creating a wiring nightmare for your self later.
The memory wire you will have to run to the battery. The ground can be put on any bare metal screw close to the radio. You could redo the harness by finding a four wire male and female plug that will fit together and hooking them up to the power memory and ground wires and running the speakers straight. If you do this cut the brown, black/blue as close to the stock harness as possible. Then put them into the new plug.
