Need help please au fairmont conversion

[imbhvn]

Okay so ive been doing my au fairmont conversion the past two days and its been doing my head in.

I plugged everything to where it goes etc, am yet to get my bcm reprogrammed.

This is whats happening

No windows work (front or rear) (front passenger switch lights up thats all)
No stereo, Will light up and get power when i press door lock on dash but only for a second.
No indicators only hazards
The lights in the door trims dont work (globes are fine)
Interior light doesnt turn on when drivers door is opened
Drivers electric seat doesn't work.

I had a look at the drivers side door plugs that plug into the main loom, and it seems that all the wires are back to front, eg thick wires are running into thin wires visa versa. Is there a difference between series 1 2 and 3 door looms? as that would eliminate a majority of my issues, i have tomorrow to get everything working or i have no way to and from work!

All help GREATLY appreciated! Thank-you in advance!

Tim.
