As you may have read ive been having problems getting my headunit to come on.
Look at this pic....
The brown wire continues with the loom behind the dash
But the RED/Yellow wire which comes from the connector, then gets taped up with the orange, but i had a good look last night and it gets taped up with ANOTHER red cable!!!! which continues with the loom behind the dash.
So i thought to myself "better check behind the iso block then" and there is a red wire from the bottom block of the iso block that has been snipped about 5cm away from the block!!!
NO WONDER IT WOULDNT WORK!
I will have to reconnect the red wire to the back of the block with a chocoblock? will that do?
But due to the fact that this iso block has been tampered with before from a previous owner, does anyone have any diagrams to show what colours i should have going to the back of the iso block (as there are 10-15 different cables)
And also i have a multimeter so does anyone have any information on what results i should get across each terminal.
Thanks for the help guys but one last question! 
Also would it have damaged the headunit by not having a red terminated into the iso block, when the headunit was plugged into the iso block i heared the motor turning/laser moving in the headunit but the screen would not come on, even after i pressed the souce (on) button.
Thanks again

chocoblock will work. Probably should get an autoelectrician out or anyone you know with a soldering iron.

the iso block in your hand looks looks like it has the speaker wires on it? and they all look intact?? and that is just for speakers it looks like you dont have the iso connector for the power/earth? and these wires have been connected directly to the loom,
are all of the wires in the car loom cut? or just a couple (live/earth)
as you should be able to plug that block into the one on the loom (one with 8 terminals in) and that should then run your speakers,
then you just need to check that the colours from the headunit are connected to the right sources
Red & Yellow (one is switched live and one perm live) cant remember which way around,
Brown - Earth
Orange will be illumination if you want to wire this to the side lights you can or u could wire it to the ignition live,
