friend of mine asked if i wanted to change a heater matrix on a disco,i declined his kind offer on the grounds that it was going to be a nightmare
2 weeks later i saw him,up to his knees in nuts,bolts and plastic clips
today he rang up to tell me water had got into the ecu under the seat,warning lights everywhere, it wont start and the owner is a tad upset.
sound of a door being slammed and a single gun shot

Bit odd that an off-road vehicle has that kind of electrics in a place where water could easily flow and not be covered...

hope my ecu isn't down there I've dropped a few coke bottles in my time, so has my son
