q7 abt bradford

Hi Everyone I am new to the forum and i purchased a q7 s-line 3 weeks ago I have decided to do a facelift conversion and bought all parts. I then removed the white wrap, lucky enough to take it off without damaging anything underneath, but its still having a full blow over and any minor imperfections removed from the exterior, not many. In the pictures i just test fitted everything and with the parts being original they fit like a glove. The only part i need some advice on is the headlight wiring. i am going from halogen to bi-xenon drl and believe i have to purchase some adaptors from kufatec, but apart from them being plug and play there are 4 wires that need to be connected inside the car under the drivers footwell to activate the drl and also the bi-xenon shutter. can anyone help or shed some light on this for me Thanks in advance
