HeatPane Question/window installation

When I bought my car, it was in boxes, as was all the glass. I'm getting both the headliner and the glass installed on Thursday. Hooraaa!!!
At any rate, I really need to know what spade wires go where on the rear coupe glass.
The wires are on a zip tie...So I'm very lost.
Also, Does the rear speaker shelf have to be in the car BEFORE the rear glass goes in???

Thanks guys, HAPPY happy, Merry MERRY!
