tuning box on pd engine

[AaronH]

Hi guys, new to the forum but would like to pick your brains. 

Got a tuning box for my 2007 a4 2.0tdi 140 b7. Now im almost certain its a PD engine, but i cant for the life in me find where to connect the plug from the box. 

I know many dont like the boxs but im trialling it before i look into a remap.

If anyone has put a tuning box onto their car id be grateful for your advice.

Ive attached a picture of the engine.

 

Cheers

Not sure I will be able to help directly here but give us some more information, what's the tuning box you bought and maybe post a picture  of it too.
