H/U Wiring trouble 06 Dodge Charger

[ShagggDiesel 25]

I'm in the process if replacing a factory head unit in a guys 2006 Dodge Charger. I wen't to the local dealer to get a wiring harness because it was the only place around that carries the model that I needed. When I asked for it, he told me that the part I needed was $140 however, he would sell me a standard harness that would work for 25, but I would have to run a remote wire to the fuse panel under the hood. He said that the ignition wire would be useless and I would have to do something along the lines of wiring the remote, ignition (red) on the HU, and the remote from the fuse panel all together to get it to work. This had me puzzled, but I tried it anyway.. with no success. I also tried using the ignition wire and wiring the harness to the HU normally like you would to any other vehicle with no success. I can press power on the HU and it will come on and display the time for about 3 seconds and then power off, but that's all. I even tried wiring the constant power and the ignition wire together just to get the HU to power on, and STILL nothing. I checked ALL the fuses in the fuse panel to make sure none were blown. At this point I don't know what else to but to ask you guys for some advice on other routes to take.

The HU I'm working with is a JVC KD-R310. Wal Mart material.

If you need a constant why not just wire to your battery?

I didn't mean constant, I should probably change that. I meant that the HU won't stay on. I have no switched power source.. Hence the reasoning for wiring to the fuse panel? Which wire should be ran to the fuse panel though? I figured it would obviously be the ignition (red) on the harness on the H/U but that didn't work so idk.
