Retrofitting LCI Xenon Corona Headlights To Pre-LCI E70, help / input required

[treelo_meelo]

Hello to everybody, i'm a new member who recently acquired a 2007 E70 X5 3.0D model in the UK. The car was purchased extremely cheaply and is a cracking motor, enjoying using it daily. However to my surprise not only has it not got factory Bluetooth, but it doesn't have Xenon's either! I assumed all came with it from factory, I've owned lots of bm's last being a 635D M Sport and all had xenon's fitted.

Anyway I thought it's no biggy,as the car was very cheap so I've thought about looking into retrofitting the xenon headlights. Not the standard xenons but the current LCI LED Corona types as fitted to all current E70 models. My car has halogen headlights fitted currently but does have the headlight wash function fitted, this I thought would be very helpful for the retrofit.

I've done as much research as I could and haven't really found too much, the questions been asked many times but never fully answered or completed it seems. I know delviacv2 from this forum successfully retrofitted these LED corona's xenons to his x5 but I believe that he already had standard xenons fitted already. I realise that there will be a number of things required and I've already acquired a large portion of these, I have a pair of the headlights, complete with all xenon ballast packs, control units and bulbs fitted, absolutely complete ready to fit. I've also ordered an FRM3 from a 2012 x5 that will be required to be fitted also I believe. The main stumbling block that i'm thinking will be the headlight connectors, I assume the halogen pre-lci are going to be quite different from the ones required for the xenons. This is where I would like as much help and input as possible from you guys the experts really. What exactly do I need to do next, where can I obtain the diagrams for the wirings etc? and do you know how easy setting up the self levelling would be? Is the wiring already in place? I read it possibly is on another forum?

I'm willing to do the work required, no matter how big or small it is. The headlights I've got aren't adaptive xenons, they are just the non adaptive types from a 2012 I believe. I'm hoping if possible to be able to complete this retrofit and then put together some sort of guide for others in the future to then be able to attempt if they wanted.

Any help and input would be greatly appreciated, I will need someone to help me with the coding too, I have autologic diagnostics which I use for my own business but I believe i'll need someone to do the coding remotely as I don't have a cable for the pc connection. I'll of course pay for this to be done and anything else required, look forward to your responses and sorry for the epic first post! thanks! :P
