Radio Ignition hot

[BADFISH]

So, got my new Pioneer DEH-P5200HD yesterday but ran into power issue during the install. I twisted all my wires together to test the radio and make sure connections are good for speakers and what not before they are soldered. Well go to power it on and nothing... Bust out the old test light getting a constant power from the battery but no ignition hot. I check other wires thanking I may have the wrong one but I didn't. I check the fuse, it's good. then I check for power at the fuse and I get absolutely nothing. I assume the wire to the fuse box from the ignition switch is bad as the ignition switch was just replaced. Does anyone know what color the wire from the ignition to the fuse box is for the radio? Or what would be the best place to tap for an ignition hot...
