i have now replaced the stalk unit on the car and the wiring terminal that had melted but the problem is still here

when i press the brake pedal fuse number 13 blows (Fuse 13 is bottom row in middle) 10Amp

from the BOO running guide fuse 13 runs these

Instrument Panel Power + Key

Engine Oil Control Unit (TD105)

now ive had a thought that maybe a wire further back has melted connecting another to it but im unsure of this ill have to check all the cable right the way back

but another thing has started to happen as well
when i lock the doors with the alarm fob the rear lights flash all the bulbs at the same time but it used to be only the indicators that did this

thats about all i can think of at the moment
 
there is a short on the rear light circuits, the indicators and brake lights are directly connected at some point. you need to find this fault and isolate both circuits.

its usually at one of the rear light connectors. try disconnecting both rear light clusters then see if pressing the brake pedal blows the fuse, if it still does you know the problem is not in the lights. if it doesnt blow one of the rear lights is the problem, try connecting either to find out which is the problem. when you find the problem light you need to find where the short is ovvuring, expect to see corroded contacts on the inside of where the connector goes. if it sint either light check both the wiring connectors for corrosion. failing that its time to get the multimeter out.
