I see. Perhaps it's better to focus on completing the retrofit of the BCM first.
Or you could check some things like whether the wiring is transmitting +12V to T73a/37 in auto setting.

all other exterior lights work as intended, at the front?

Yes but not in auto light mode
If set to side lights only, just side lights are on.
if set to headlights on, then dipped beam comes on, when stalk is pressed or flashed, full beams come on
but nothing in auto mode by the looks of things, other than the side lights being permanently on

I see. I'll leave it to ciclo to have a look at your coding.

i'm just guessing at this point, but you could have a look at byte 18 and try something like '61'.

Hi iichel,
Been doing some digging around to try bridge the gap we are having, i'd like your opinion on the coding for byte 13.
Byte 13 according to your coding is 0B
3C8829EFC8F32500932000007E0B1EC8008061]0F60880000200000000000
From what i've found online (see below)
The coding matches currently for what is ticked in the image, however bit 7 is unchecked, surely this would affect the light sensor working, please let me know your thoughts
Cheers
Matt

I have also uploaded the T6 BCM pinout to the drive link i've previously shared, I have compared it to all the wiring I have done and it all seems okay, I must be missing something

Update
Was battery voltage, got it to accept long coding, e20 interior lighting now works. Side lights still on permanently though
Changed patch of auto lights from T17/16 To T17/5. Side lights now work as expected
