Vito 2012 cdi w639 OM651 nearside Front indicator not working.

It would be involved to connect to the SAM.
The only purpose, I see, for a feed from the fuse box (Same location) to the rear, would be to feed a towing relay. But you say it connects to the flash lamp.

Yes what i can see it seems to go directly in to the indicator lamp. But i must double check... what if it is a "ground" cable? But no it goes to the blinker bulb, the original cable is cut off and replaced with this cable..

That implies that the wiring was tested previously, and the new wire put in due to open cct.
Might you have micies chewing your wiring?

Yes true... no not what i can see.. someone said there must be a cable break somewhere, but isnt this possible to check with multimeter, fex take out the ground from the whole rear light and then check if any cables conducts to the frame(ground)?

Brown wires are the -ve. Easy enough to check heir continuity to chassis.

For other wires you need identify both ends, by colour. Then with them free of end device, probe at each end and check continuity.

Ok easy to say, but worse to do.. brown = v (12v postive)?

-ve is negative.
+ve is positive.

So testing any brown to chassis is one probe on the disconnected wire, the other probe to a reliable bolt (or similar into the chassis. The result should be a very low ohm reading.

Ah ok, many tnx.. must try to test these... maybe disconnect the big cable bundle connections from the SAM and use the connection output pins to test from the front end of car.
