Need Your Help Please!!!

Lastnight A friend of mine was going to put a stereo in my car. I have a 2004 Mazda 3s. We were going to put a amp and subs in the back. This was a disaster from the beginning with many signs of not to do it. Half way through I'm looking at my dash lights and all the idiot lights are on when car is running. The brake light, check engine light, power steering light, and TPS light were all on and would not go off. We double checked everything and could not find a problem. We just ran the 4 guage power wire form battery to amp and remote wire for the amp from a 10 amp fuse in fuse box that was for the ignition. Any help would be greatly appreciated. On the way home my power steering was not working and speedo not working also. Oh, by the way I got angry and all the s*** came out including a custom sub box that took about 40 hours to build. thanks Jeremy

i'm not sure if it matters but i think the remote wire goes to your radio but since its just a 12V trigger i don't know. I would check all the fuses in the box where you ran the remote wire and see that all of them are there. Also make sure you didn't short anything out in there. aside from that i'm not sure i can offer much more. hope you get it fixed

Already checked the fuses and they are all good.

I hate to be the bearer of bad tidings, but it sounds like you fried your body control computer. If you did, it'll cost you about $1200 to replace the fuse box/computer assembly. Figure out how you did it, first. Otherwise you'll just fry the new one, too.

What you could try is just disconnect the battery for a while and let all the computers reset. If that works, great. If not, see above.

WHile the computer is unplugged, take the tap off the fuse and disconnect power and ground form the amp, tape up th epower obviously. If the car resets and is ok, then the amplifiers connections are causing a problem.

Other then tapping the fuse for ignition power, did you guys tough or mess with the ECu or fuse box in any other way? Also, often, under the hood are the cars main fuses. Be sure none of there are blwon.
