Before this, I had never replaced a window and I had no problems at all. Your hardest part is removing the old window but they give good direction on how to do that. You will need a partner for this part but just to hold the window so it doesnt fall. I had the whole thing done in three hours and that included running the wires and hiding them. No soldering and all wires are color coded for easy plug ins. Anyone interested, I would be happy to send pics.
