Earth cables Identification (1 Viewer)

[Marauder]

Burstner T620 on 2008 Ducato 130mj with Electroblok 99 and AD-01

Whilst fitting new starting battery I noticed two (quite thick) brown cables attached to the negative (earth) Battery terminal, these both disappear under the plastic coverings so I am unable to trace them.

Can anyone identify their function pls ?

Thanks

Steve

They quite possibly go to make general earth points elsewhere in the vehicle save having them all nrought right back to the battery?

Most likely common earth tails

On our hymer ,with electrobock, I believe they go to the electroblock, one for fridge, the other for charging. Brown is often the ground cable or negative in electroblock ,german,wiring.
