Gauges fuse keeps blowing, windows don't work either Options

[RoadRage]

Hey guys, I'm having a bit of an issue
I took out my Control Unit thingy when i had a go at wrapping in carbon fibre


All i basically did is undo the 3 screws on the back, wrap and put back together and now next morning while driving my gauges went out while driving, Stopped and replaced the fuse but it blew instantly, I noticed the power windows don't work either however the fuse is not blown.
I took the control unit thing out and unplugged the power window (along with the lock button) and put a new fuse for the gauges and then didnt blow.


After driving for a while it was fine, but driving on the way back home on the highway the gauge went out again

I am assuming the wiring must have been tugged and something came loose when playing with the control unit... because when i check now the fuse name it says
gauges and metres, power door lock system

so nothing to do with the control unit.. maybe a loose ground?
anyone here got any ideas??
Thanks

Ok this is turning into a bigger problem...

I got in the car and the gauges were out again.. so I got a phone GPS and drove to nearest store to get some more fuses, which I did. While driving I also figured out the aftermarket cruise control wasn't working so I thought that could be the problem
On the way home the Radio started cutting out every few seconds and my dash/clock/heater lights seemed dim
Started to panic a bit and rushed home and turned the car off

I tried a new fuse and it worked and the gauges and windows are working again but I noticed the windows were going up and down reaaaaaaal slow..
I looked at the headunit and saw that If i turn on something else in the car that uses power, the Headunit cuts out
So if the unit is on and I turn on the lights/high beams.. the headunit cuts out

I've had a play with every wire under the dash to see if tugging/pushing it cuts out the gauges but its still working fine.
Go start the car and now the battery is dead...

Is the battery fried, causing all this, or is there a short somewhere that I cannot locate?
