Heated rear window wiring question

[Steve C]

Hi

I have a heated rear window from my old to go into my new 1303. As we didn't have heated rear windows from factory down here I have no idea what the wiring looked like when it was hooked up.

I don't need an actual wiring diagram if you have a photo or just explain what sort of terminals were used and how the positive and the earth wire are routed.
