200 tdi rewiring. should i be scared

Hi there.. i am currently stripping my 90 in prep for rebuild. i feel that i can cope with bodyworks nd mechanical....but electrics..not really my medium.
She's currently stripped of all interior and the electrics look rather crude..lots of connector blocks and leccy tape. am i better of relacing the whole loom and how easy is this..
thanks

You will find most landy's are very botched on the wiring and most still kinda work, however, if you're doing a full re-build I would personally put a new loom in, it will make it all "right" and easier to fault in the future rather than trying to work out years of bodges.

just about what i was thinking.... Thank you
