Skoda superb 3v3 SE tailgate

Hello everyone, can anyone that has extended tail lights tell me the part number variation of their tailgate wiring loom?

I know that main part number is 3v5 971 147    but i need the ident variation at the end (the letter or letters)

My aim is to achieve extended tail lights, is no difference from the same trim that has halogen tail lights and has them active as a extra option for the 155£ as far as i could tell the difference is in the loom splicing... the car i compared my one with is missing the label on the loom.
