what 4 door escort was that Carlo?
Peice of piss really, take out the dash , unclip the loom from everywhere. do not cut any earths if you can avoid it. Prise up the fuse board section of the fuse box and withdraw the loom , as the haynes says , refitting is the reversal of removal.
Make sure you keep the seal in place if you take out the full fuse box, this will stop the water coming in to your footwell.
when refitting the loom , the wires sit in place here they are ment to go , but it wont do any harm in labeling it up as you go along before you remove it
