V5 2.3 to 1.8t aum

[Maxine90]

Stuck here a little if anyone has any ideas
Mk4 golf v5 2.3 manual 150bhp
Swapping to 1.8t aum from tt
Wiring loom doesn’t split or unlink anywhere
Currently stripped the car to bare metal inside
Anyone any ideas before I just buy a whole new loom
Ps loom is in full working order and we have the loom from the 1.8t just can’t seem to split our current loom from the ecu to the inside eletrical part

That's quite a niche requirement; best/closest source of info for 1.8T wiring looms is probably the MK2 Golf 20VT group on Facebook.
