Default Windows, locks, and el gauges won't work, help!

Hey all,
As many of you may know, I have a 4th gen lude and I was having it tuned and all of the sudden the gauges wouldn't turn on, the windows and sunroof wouldn't roll up or down, and the locks were malfunctioning. The only thing electronically that was altered while we were tuning was the wiring of the map sensor which I had messed up.... Otherwise, all fuses are good and all that lights up on the dash is a battery light, which is strange.

Also, headlights and center console (cig. lighter and cd player) all function...
These problems to me don't seem linked but they all happened at once, any opinions? If you have any questions for me just let me know. Thanks in advance guys...
Max

Does anyone think this could be the dimmer switch? Thats what I've been lead to however I don't know where its located or anything so any help would be appreciated. I also read something about a multiplex unit, however I don't know what that is or does or where its located..... Any help would be appreciated!
Thanks
Max

No fuses are blown?

Nope, all fuses checked out alright, I also read about a meter fuse, is that on the main fuse blocks? (interior and engine)

No I actually haven't, I wouldn't think it would do anything, but I guess its worth a try....

I wish there was a simple thing to check that I could think of, but now it looks like you'll probably just have to get a factory service manual and go through the wiring diagrams...

I have the factory service manual and going through the wiring diagrams just isn't helping me, I'm not sure where to look for it....

I couldn't tell you, all I know is that it was mentioned and I'm still fuzzy as to what it actually does....

Start with one of the things that isn't working and test all the wires going into it (some are power, some are ground, some only have power when a switch is on, etc). When you find a wire that's not getting what it should, then use the diagrams to find out where it goes to and check the next thing in line...eventually you'll find the problem.
