Weird Rear Light Situation

[cammmy]

Hi All, looking for some advice.

The previous owner of my car had the rear lights modified to remove the dead LED boards and replace them with sockets/LED bulbs. Long story short, the red outer lens fell off one, I bought two new (facelift) units but when I went to fit them, the harness doesn't match the lights. The weird thing is, the harness doesn't match the old non-facelift lights either (images attached). Has someone changed the plug on the harness at some point? I've ordered pig tails for the new lights, is there a wiring diagram available somewhere for these?

Thanks
