people help is needed

right i have just converted my engine to a 2.0 turbo gsi. i had to change the engine loom and dash loom, i have got the car running all lights fogs and wipers working fine all functions except the electric windows.

when putting the dash loom in, does any1 know if the blue plug near the passengers side is anything to do with the windows as it doesnt connect to anything.

it looks like it shud connect to the car bay loom but does that have anything to do with sri 2.0 electric windows??
