It is taped into the wiring loom along the inside
of the sill on passenger side under the carpet. It's
a corrugated black plastic line. It has joins under the
dash, under rear footwell, and in boot above the
toolkit, all of which can pop off causing big leaks.
If that's your prob I glued all the joins with epoxy
resin and they're now fine. It can also split where
the loom enters the tailgate and can pop off the
back of the wiper motor inside tailgate. Mine has
done all of the above!
