I am hooking up an aftermarket radio and for some reason the Orange wire(constant has no power now... I touched it by mistake and it sparked but the fuse is good. Where else can this break? The radio fuse has no power to the fuse box.

 

Check both the fuse on the head unit and the cars fuse block. I dont know which you checked. hope it helps!

 

Both are good I had to run a new wire from batt to get it to work..neither the aux or constant have power now.

 

O and where did you guys buy your head unit dash install kit?? I got a universal GM one and it is a POS and need a better one.

 

I did the same thing in my Trans Am. Did you check the "convenience center" under the drivers side of the dash? There is another 20 amp for the radio in there. Not to be confused with the fuse block, convenience center is next to it. you will see two tabs, pull down and a little block will come down. there is a couple of relays, and more fuses. I would bet any money that's your problem.

here, I just found a pic I took of my trans am when I had the same problem. I have a red circle around where the fuse was.

 

you gotta love the room they left for us wiring freaks under the dash of these 3rd gens.... put a security system and a gps mapping system in mine (so nobody can steal it again) and my plate is bulging a bit... don't like it, but have no choice on it....
