Audi Wiring Diagram help

[warp_speed]

I'm planning in retrofitting a rear boot socket, I've got the wiring diagrams from audi and other sources. Problem is I don't know where two connectors are located. They are

A52 Plus connection 2 (30) in dash panel wiring harness
249 Eath connection 2 in interior wiring harness

Does anyone know where these connectors are and how to read the bentley/audi wiring diagrams?

Thanks

A very frustrating explanation of the connecting points regarding all VAG wiring diagrams,there is no exact point given to where the soldered joints are in the harness,which means stripping the harness to find the joint.In most circumstances,personally i just run a new wire.

they are node contacts which means numerous supply 30 connections.They can be anywhere but in general there near j519 but you need to peel the loom web tape back to locate.
If your missing a 30 and the circuit isnt shorting then cut out and run a fused 30 supply
The interior will be in the loom near the convenience control unit nsf floor
The earth will be nsf footwell A pillar or rear inner wheel arch/boot area
