Default electrical help needed!

Ok, so upon trying to reinstall my head unit today, i pulled something from inside the dash. As a result neither the radio nor the climate control unit turns on. I know the red 12V line that goes to the radio is no longer working, as the light from my turbo gauge no longer works and that is where it is drawing the power from. All the fuses are in good condition. My turbo timer also is no longer working, and i think that's connected to one of the posts next to the fuse box. what might i have pulled? TIA...

Ok here's what you wanna do, read all instructions before starting:

1. You need to replace the 12V distributer unit located just underneath the fuse box. One rusted unit can cause quirks throughout the engine.
2. Splice the green AC wire running fron the fuse to the air conditioning wire with the blue AC wire, and then split the resulting line. This should take out the power source confusion between the two units.
3. Detatch the left headlight unit, or whichever unit is closest to the fuse box in order to give yourself more access to wires running along the front fender. You're going to need to check those to make sure there are no splits in the line.
4. Ignore all this I have no clue what I'm talking about.

I hope this helps

Default Here

Check your wiring everything you connected or is connected should be wired in parallel not in series. If you have voltmeter use it, if you don't know how to use it email me.....

so, here's what i've figured so far- the 30x post next to the yellow 75x is no longer working- either that or my turbo timer's fried. the cigarette lighter next to the ashtray still works. what could possibly have been pulled out?
