BROWN CABLES LHD CYLINDER BANK 1.9 WC

[Orangebug]

I have 1986 camper 1.9 water cooled. Whilst cleaning earths etc to restore temperature guage - now working with full range, I came across two brown cables which come from the loom on the lhd side of engine bay - each runs down the front and back of the lhd cylinder bank. I was not able to see the final end of the cables - the wires are brown -earth like - are they earths ?
