electrolux (LUX 5000)?

problem with electolux vacuum cleaner - cannister style LUX5000. i took it apart to fix the retracting cord, which i fixed. But when i went to reassemle, one of the connections came undone. long story short, i can't seem to figure out where this connection goes, and how the wiring works. it looks really simple but... From the switch, there are only 2 black wires. One goes to the motor, and the other connects to a "connector" attached to the canister. There is also a black wire running from the "connector" to the motor. There is also a white and black wire running from the motor to the front part of the vacuum cleaner (the cover housing the bag). in summary, the motor has 4 wires attached to it...the black and white coming from the front part of the machine, the black coming from the "connector", and the black coming from the switch. seems like i am ok with the black and white coming from the front of the vacuum cleaner (the cover housing the bag). the problem is the other 2 black wires going to the motor. any help would be awesome.
