It's been over a year now so the details are a little fuzzy.

First, I examined the breaking points. I looked to see which ribbon lined up correctly with the torn pieces. This was sort of like a puzzle, I held the pieces together and it was pretty clear.

Second, I believe there was only 1 way all the ribbons (wires) can connect together. The ribbons a layered, meaning if you don't connect them to the appropriate places you won't be able to put everything back together.

So basically try to visualize how it will be reassembled and it should become clear where each ribbons (wires) needs to connect.
