Disco 4 (LR4) Removal of Central Junction Box

Hi Fellow landy owners,
Whilst tracing wires to the Central Junction Box for a Seat Memory problem I came across water in the wire loom channel on the passenger side. I checked the sunroof drain as per youtube video and the rubber nipple under the mudguard has perished and dropped inside. Is there any tips regarding removing the Central junction Box. I am worried about causing more electrical problems. looking forward for your superior advice.

Have a search on the D3 forum, there is literally laods on there, also look at the wiki section which is under the word disco at the top of the home page.
From what I have read its a right fcukwit job and you need childs hands to get the plugs back on!

I have got to look at mine again as last few mornings the screen has been wet inside and this morning was frozen inside!
