brake pedal basically turns on the light switch.

Unplug the harness to the tailight you just put the bulb in, does it still happen?
If it does, try unplugging the CPU, if that doesn't stop it, plug the cpu back in and unplug the headlight switch.
It sounds like your brake light circuit is shorted to parking and dash light circuit somehow.
I have a feelin it's back at the tailight, or your harnessto the headlight switch could have fried.
If your harness is bad, your headlight switch could be too. Pele rebuilds headlight switches and will install a relay in a new harness so it won't fry.

also i'm ready for my emission testing and i'm tricking the air pump to be on all the time. but will this electrical issue that i'm having fail me at the smoq testing? when the light switch is turned to the first setting the brake problem is un-noticible since all the lights are on already.

THANKS thats the best advice i've gotten. i'm going to try this tomorrow. today i replaced the bulb again just incase it was bad. and i checked really closely to see if i accidentally stripped some wires but they are clean and in good condition.

and the smog center tried to fail my friends mustang for having tires to wide even though he was running the stock gt model which his car was. so i thought maybe they would make a deal out of this. because of safety or something.

ok so i understand what you mean the cpu not causing this problem. what do you mean the green wire is catalyst?

The Green wire splits and goes to a number of other items besides the brake lights and they are the cruise control unit, ABS unit and the shiftlock actuator (auto transmission). From looking at your S5 wiring diagram the Green wire at these items does "not appear" to come in contact with the wires that turn on the dash lights, side markers etc.

after more searching I have found a thread were the guy was getting no power to the break lights or other lights when he turned the light switch on only when he would press the brake the break lights came on and nothing else. I know his problem is basically the oppisite of mine but it might be the same issue. He was told it could be a harness attached behind the switch or the light switch it's self.

Go back and take out the light bulb you put in...
In fact, take out all the lights in the tail lights...
Double check to make sure that 1156 bulbs are in 1156 sockets... (ONE contact on the bottom!)
Double check to make sure that 1157 bulbs are in 1157 sockets... (TWO contacts on the bottom!)
It sounds like you have a 1156 bulb (Reverse, turn signal) in a 1157 bulb socket. (Tail Marker/Brake)
If this is the case, then when you step on the brakes, the pedal will send power to the brake lights... The wrong bulb will send power back through the marker light circuit and make the interior lights come on.

and see if the brake lights turn on by themselves. Another thing you could do is to pull the Stop fuse and press on the brakes after the headlight switch has been turned to the first position and see if they (brake lights) turn on. There are also things you could do to narrow down the source of your problem as being a front harness problem or a rear harness problem. Lastly, you said your light show occured with the door open. Does it occur as well with the door closed?

come to think about it my rear right turn signal has always been just a little brighter then my left one. So maybe when I fixed the brake lights and completed the circuit it opened up the old problem with the turn signals having the wrong bulb. Ah why did I forget about that. I'll let you guys know if that fixed it. =)
thanks Pele!
thanks Pele!

the turn signal I mentioned being brighter well it turns out there was a red bulb in there, but no part #. So I replaced the light bulbs except the reverse lights (i forgot to buy them) and nothing problem still there. The harnes from the lights is also good and I took a look at the switch but it was cover in plastic. Oh and the problem keeps happening even with the light switch removed.
So for today I moved on to the new speedometer cable I bought and tricked the airpump to pump air into the cat all the time. And did some tunning on the idel screw on top of the intake. :=): ready for emision
it happens with the door open or closed and the beeping was because the door was open so basically it was just reminding me to turn my ligts off. Well I'll keep searching.
note: I haven't removed the p/s computer cause I'm not sure where it is under the dash. ( to much wires) just further info.

Satch is doing a great job but maybe something is being overlooked here.
Let me ask you this: Was the light burnt out when you got the car. or been that way for a long time and you finally changed it?
OR
Was the bulb working fine and then burnt out all of a sudden?
If the answer to the first question is yes your cpu is and has probably been f'ed up for awhile.
Yes to the second question means you have a serious new problem. Do what satch has posted already that's exactly how you troubleshoot this kind of problem.
On a side note I was once working on a transmission and the case wouldn't open even though there was nothing holding it together. I got mad scooped it up and threw it across my yard. It landed in the grass bounced twice and popped open with no damage. So what I'm thinking is you should throw your car across the yard. Hell you never know.
Also please don't tell me you put a 1156 bulb in a 1157 bulb socket or vise versa because then I'm going to kill myself. I now have a shotgun in my mouth awaiting your answer. I'll only remove it to take a **** I feel coming on.

How about turning the headlight switch to the first position as suggested and see if this triggers the brake lights to turn on. If the Green wire at the Stop light switch receives voltage when the pedal is depressed and this voltage is being passed onto other wires because they are possibly frayed then logic would dictate that this is not a one way street but more like a two way street such that if the voltage from the Green wire can share its voltage with other wires then the other wires can share its voltage with the Green wire. Make sense? This test would take all of five seconds to do.

I swear I'll do it. The shotgun was in the way while I was peeing so I had to set it on the counter.
Check those bulbs. Also sometimes the 1157 bulb will go in backwards on messed up sockets and cause it to half *** work. Take it out turn in 180 degrees and put it back.
I'm talking about when it sits diagonal in there.
Chuk Chuk.......Oh god spare me let it be an actual wiring problem not a bulb.

^omg it was the light bulb I had them reversed! Lol just kidding I checked the bulbs like 3 times already. And yes the brakes do turn on when brake is applied and switch is on. So do turn signals. The bulb was already out when I bought the car. And I replaced now that the build is done.
wrong bulbs: no
light switch: no
wires crossed near the bulb: no
tear and wear on harness near light switch: no
cpu: not tested
rear harness: not tested
front harness: not tested
I'll check more tomorrow since school and work won't be in the way. Thanks for everyones help.

you could have the bulb(s) in opposite. what i mean is when you insert the bulb into the socket, make sure that the tabs on the bulb match the inserts on the bulb holder(s). i have done this and it will make your dash lights come on.
