Constant power wire in the radio not working, ideas?

So, my radio harness has been FUBAR'd since I got the car, and just started cleaning it up last night ( I swear I should have a camera on me at all times) Soldered and heatshrinked color coded wires back on the loom so they're the same length. Anywho, here's the issue;


RED/Black = Constant (battery)
Blue and some other color is the switched

Switched power source works dandy. Constant has NO power going through. Before the answer of (ya theres a short somewhere) I want to see if there are any other inline fuses somewhere other than whats in the driver side fuse box (Which is fine, when that blows, the switched power goes dead, and that works).

Where does the constant lead to? Any other accessories that are tied in to it? Chasing this single wire for a break location is impossible. Any factory diagram that will show me the path of the wire?

Spanks!


Edit: Just to note, I had a multimeter with me, I tested ALL the wires for power, car on, even the speakers for sh!ts. The switched is the only one that is drawing power.

Get a FSM and then just start tracing the wire that is all you really can do unless you want to run a new wire from the where ever that one starts. For some reason I can't think of the word right now.

really, every time i do a stereo, i run a new contant wire direct from the battery. Put a fuse in the wire each side of the firewall and you are good. Saves hassles with the factory loom.

Check all your underhood fuses too. I see people coming into circuit city where I work thinking radios are blown and its a fuse under the hood. Best bet is to test all of them with a multimeter by making sure you've got the same power on each side of the fuse.
