thanks for the advice rhett. i would like to keep replacing the entire loom to a last resort, as i wouldn't like to take on such a big task myself so if it came to that i would have to face a big garage bill! so in the mean time i'm going to assume i will be able to source connectors etc to replace the damaged section.
i've had a closer look at the wiring damage now and if CANBUS is just 2 wires for data and 2 for power then i think i have identified the break in those, but i also have a much bigger problems too
i realise this is a pretty big request, but would anybody with a 147 be able to look at the wiring behind the glovebox in the passenger footwell and take pictures of it for me please? i have noted down what wires appear to be damaged and their locations. i cannot tell where most of these damaged wires should connect to (presumably, mostly each other) so if possible would somebody with a bit of free time be able to try and locate the colours of the wires i have mentioned and take pictures of, or describe where they should join up to?
anyway here are the wires i can see, sorry if they don't make much sense but i thought writing them down might even just help myself to organise a bit better:
1) from enginebay through small rubber socket in firewall:
2 x twisted pairs (colour unknown) - possibly to CANBUS down left hand side of passenger seat (section 2)?
1 x thick (colour unknown), to (and through) small burnt plastic block, on to extended right of footwell section
6 x thin (colour unknown but might have been blue?)
2) left of passenger footwell:
1 x thick black earth to ?
2 x twisted pairs black possibly to CANBUS in (section 1)?
3) right of passenger footwell (left of centre console):
1 x black into 2 x thick blacks (possibly earths) to?
1 x black into ? (possibly above?)
1 x blue/black to?
1 x blue/yellow to?
1 x blue/grey to?
2 x medium thickness red/green (1 into extended right footwell (section 5), 1 into burnt clump (section 4)).
1 x medium thickness blue/yellow to burnt clump (section 4)
1 x blue/white into extended right footwell (section 5)
1 x blue/pink into extended right footwell (section 5)
1 x white into extended right footwell (section 5)
1 x yellow/grey into extended right footwell (section 5)
1 x blue/green to burnt clump (section 4)
1 x purple/black to burnt clump (section 4)
1 x pink/white to burnt clump (section 4)
1 x pink/black to burnt clump (section 4)
1 x brown/black to burnt clump (section 4)
1 x brown/yellow burnt clump (section 4)
4) burnt clump:
1 x medium thickness red/green to?
1 x medium thickness blue/yellow to?
1 x blue/green to?
1 x purple/black to?
1 x pink/white to?
1 x pink/black to?
1 x brown/black to?
1 x brown/yellow to?
5) extended right footwell (left of centre console but further out than section 3):
? total unidentifiable
1 x thick red/black to? from?
1 x blue/white to?
1 x blue/pink to?
1 x white to?
1 x yellow/grey to?
i believe some of those would have linked to what i think would be the heater motor as this is missing from mine so i cannot even hazard a guess. is anybody able to tell from the colours where the "burnt clump" might have gone to? and what the "small burnt plastic block" may have been at one time?
