Default 68 Corvette power windows wiring

Hey guys, just started installing my new painless wiring harness. I have a old diagram from asking a few years ago but it seems to leave out the power windows. I need to know how this operates. Does anyone have diagram? I assume I would still use the stock relays, just getting my power from the new harness. Slowly tackling this restoration project, any help please.

I've searched for about an hour and only found 2 blurry pictures and a very sad drawing.

Thanks

almost any year C3 power window harness will work,
find a used "power window harness" it is then plug and play, to switches and motors.
I have done this retrofit what is your questions ?

So restoring a 1968 coupe with power windows. This was a barn find, so just started cleaning this week. Doors, not yet.

What is this third wire for?

Here's a diagram for PW I used on my 1972.
Maybe this will help?

That is the ground wire that should connect to a male spade on the power window motor. Lou.

Your motor has the 3936359 pad as shown in the AIM attached. I've never seen one before

You can try this document. It says 1969, but they are all basically the same.

We removed all of the old wiring and installed a new Lectric Limited wiring harness.
