Fault codes help please

Gents
Just had the gaylander on the diagnostic tester and its showing two codes
P0500 which is the gearbox speed probes. Have done a bit of research it appears this may be caused by water/ dirt / corrosion in the multi plug to the gearbox. Can any of you fine chaps give me a clue as to where I may find this multi plug.
Code P1E00 also shows up as Unknown any ideas?
thanks

I'm guessing it's a td4 auto then. in the engine bay left hand side as you look at vehicle, halfway between radiator and end of engine, you look down onto back of connector.

hippo did a mod to this, there are some piccies on here

I googled the fault code, came up with can-bus error.

Thanks for that It is a 03 plate TD4 manual. After more research and digging it appears that the Vehicle speed sensor is at fault but I can't find its location any help would be greatly recieved
thanks

When yer ses vehicle speed sensor, does yer mean the speed sensor in the auto?

Ere's the connectors. The collar on one part twists as they join together. Mine came apart so I modded it.

Did you fix the problem which caused the P0500 code error?
