Those are crappy cell phone pics.
I was trying to photograph behind the plastic parts still in place, so they will be updated with better photos.
Also the rear seat was soaking wet so I found a leak from the trunk in my car so that's a plus....
All you need to have to generally work on these cars successfully is the factory service manual, and gnttype.org, and of course this site.
I assumed factory glass but of course there are aftermarket solutions as well.
If you wanted to skip the factory switch and associated wiring you could use a 12 volt triggered timed relay with 30-40A contacts and a trigger switch mounted anywhere you like for it, but the factory stuff just plain works good.
You'd still need a heavy wire from the fuse panel/timed relay out to the glass no matter how you wire it up and the good ground.
