I haven't look into it properly yet, at the minute I'm just focused on sourcing other bits. I've got already RVC kit, Quad AC, DAB, DTV, new aerial amplifier, Auto Boot, lights of course, AMI and now I'm looking into RSE, soft close and i even looked into fridge which I'm not a fan of :Confused:

So as soon I have all the kits I will look into each of them to see what else do I need and then pick a day or few to fit it all in one go.

The only different thing I have noticed quickly is that S8/W12 LED headlights are back to T10 (10pin) connector. My current cornering bi-xenon AFS lights use 14pin plug, I assume less pins is down to the fact that on new lights LED part does DRL and side lights functions so all needs doing is changing (rewiring) plugs and that it.
Note that you don't need to change J519 even if you go from halogen only lights to the one I have.
Also, my current headlights are already coded as LED ones and they function exactly the same as the one I'm going to fit, but with proper LED side.

So no, you don't need to do anything to the on board power supply, possibly remove a wire or two (sidelight) on the 23pin plug, but I don't see why if it's already all coded and working as the OEM LED DRL headlights with AFS and xenon cornering functions.

I'm all unexpectedly feeling work shy...

That's a lot of retro fits!

I'd be interested in the quad AC as I've only the front dual zone.

I will provide full wiring, locations and parts list for each retrofit which hasn't been covered here already so watch this space +++

So far apart from the obvious rear extra heaters in place of existing ducts, rear AC CU and different rear center duct at the end of the console all looks same. Extra wiring will be obviously needed, possibly additional temp sensors, but nothing impossible so I'll update in separate thread as soon I figure it all out.
