G31 NBT retrofit - OABR query

[lordchadski76]

Hi gang,

I have what I hope is a quicky:

Upgrading from (what I believe) HU_Entry [8705952] to NBT_EVO [8736164] in 2018 ECE G31, I have a 6-pin OABR connector currently, with a white and a green cable only, labelled A42#3B.B. I am seeking confirmation or correction that these should be transferred to 20-pin OABR as pins 19 & 20.

Also I see from other folks' images that some people have found a third (black) cable, any clues where this should lead?

Any news or thoughts appreciated.

Its only these two wires that are important.

Thank you for assist.

And to double-check they should be 18 (White) and 20 (Green)?

depends on where you want to connect it. Oabr is only necessary for flashing or patching unit.
