Polo GT 3F engine conversion in mk2 golf 1.3 NZ. Need help

Hi. New here. So not sure how this works yet. But I thought I’ll give it a try. After a weeks research I can’t seem to find some information I need on a 1.3 nz to 1.3 3f engine swap. 
Recently bought the 3f engine complete with the wiring loom out of polo gt. And planing on fitting it into my mk2 golf. Which now has a 1.3 nz in it. 
And got stuck on a wiring splicing. Theres two connector plugs that connect the ECU and the engine management loom with the rest of the wiring and a fuse box. There’s the three wires that I know were they’ll need to go to on my existing loom in my golf (“brown“ wire on one of them and the “red and black” and “red and yellow” on the other)(I’ve marked them on a photo1) 

So need help with the other three 😕 

I can trace them all they way to the fuse box, to those two 20pin connectors. But that’s pretty much as far as I can go.

Anyone knows what those wires are? Can’t find any fuse box info.

Thanks
