Nice documentation, Brian.  I hope to do that some day.  Thanks!

Agreed, I'll probably do the same. Slightly off subject but I had planned on installing relays for the headlights when halogens were the norm. I'm just wondering with the prevalence of LED headlights, if relays are still recommended or even needed

Link to a short video showing my ammeter as window is raised and lowered:

It looks like it's roughly 15 amps, going to maybe 20 when the motor stalls. 
If you're not able to view that video, let me know and I'll figure out another way to post it.
15-20 is what I remember the current draw is. I think it is 20 starting, 15 moving, and 20 at stop.

Posting that video was really handy, Fotog, since I no longer have an ammeter. I guess I'll use a 40 amp fuse in case I work both windows...

Definitely looks like a relay is warranted
