Howdy folk's , just wondering if any one here has some knowledge on these escorts wiring looms ?

my problem is the electric windows ! I have a permanent live wire from the fuse board ( red with brown strip ) it has a female spade connector on the end of it (white single spade) the problem is this 12v live wire was connected to the earth wire that connects the frond drivers door interior light, (was the cause of battery drain over night ) now i have unplugged it from the earth wire i have no battery drain but also the front windows dont work at all ! when i reconnect it the battery will flatten over night but windows will work !
any help would be greatly appreciated


cheers in advance !
