From where take the CAN signal (+/-) [Polo 6c 2015]

[salas]

Hi guys,
I want to install OPS 8k system for my polo 6c 2015.
Following this diagram:

Where is the point "B390"? and what's the nearest point CAN signal (high/low) to the trunk?
Thank you..

I would say, there is none very close to the rear. Since you're doing 8K pdc, front and rear, you might as well get it from i.e. engine ECU or BCM or AFS module (if installed). Other options are airbag ECU or power steering.

then, I'll take it from the BCM (J519) T73c: 44/45.
But in reality, what do the points B390 B383 mean ?

Is there a CAN signal on the 5F module (infotainment system), and is it compatible with my case?

[iichel]

Yes there is a signal but it's not the correct can network

[salas]

Is there CAN wires behind the "glove box" for passenger airbag?
How about this ( blue plug top image)?

Behind glove box plug

[iichel]

No.

Where is the airbag ECU please?

[iichel]

It's below (all the way on the floor) if you go down from the climatronic/radio panel.

Can you show me a picture?
