1.6 jx td temp sensors wiring

[Rascal]

Currently on a 5 week uk tour with work dotted in between . van has been faultless untill yesterday when temp gauge became intermittent and lower than normal (bang in the middle except after a big hill slight increase) so i knew it was the wiring at the sensors as they are brittle and have been repaired previously.. My question is as its not clear in the bently. Can anyone send pics of the engine bay wiring as there are 3 sensors that appear to be daisy chained and as the wires have been repaired the colours are different.. So I cant quite work out what goes where..
Ill post an image as soon as it lets me.. Its playing up
Right now
