I identified the mount holes for a couple of the rear regulator brackets.

The straight, lower bar in the first image was easy.

The second image shows the bar that pivots the window up and down. I think I have located the holes to mount it. I know how this arm connects to the regulator itself.

The third image is the regulator bracket. If the top left bracket hole uses the hole just below where the glass pivots then the other two holes do not reach anything.

I have it oriented as the drawing shows it. It would not surprise me if I am holding the whole thing upside down.

I would use the original wires as well but I am using a Painless harness so it's all new anyway.

Question:
I tried matching up one of the rear window regulators today. None of the bolt holes on the regulator match the holes in the body. Is there another drawing showing how it installs?

I'll get you the whole wiring diagram. It will probably be next week once I have the final parts and I have walked off all that turkey.

For now, I will provide an image of the relay wiring that I got online for these motors. I have tested it and using the PW switch to ground the motors does work. If there are going to be any issues I will not know until I find them the hard way.

I saw the terminals on the Digikey website but the whole site was very confusing and a little misleading so I passed on it.

I did send a picture to YnZ Yesterday folks this morning. The new terminal and connector body are already being shipped to me. Thanks for that info.

FYI: Since I updated the motors in my power windows the wiring is all different. I believe all I need for each motor is one wire for power and then ground each side of the switch to the inside of the door. It cuts down on some of the wiring.

Here is a link I found to them:

https://www.te.com/usa-en/product-344469-2.html

I found a company online that makes these wire terminals but they only sold in bulk.

I doubt I could ever sell the remaining 55,992 of them.

I'll just see if I can salvage these original connections off the old wires. Better yet, I will probably just splice my new wires into the originals.

The new PW master switch came in yesterday. One of the pins is slightly bent but so it is used. I can't complain though. Its movements are like new. I am lucky it was listed for a Caddy because it was about 55% less than the switches listed for Packard.

I gave it a quick test and it worked the regulator as it should.

Now I need to locate some compatible wire connections so I can connect it the right way. I could splice into the old wires but would prefer to replace the wires if I can find the right connectors in the second image.

That extra PW switch that came with the car does not work. It is probably one of those hydraulic-style switches. The pin pattern matches up but it is not built the same way at all.

I did locate a 53-57 Cadillac switch (no bezel) that matches the Packard switch. It's made by Delta Electic just like the Packard. I'll know more when it arrives.

I am currently researching ideas for my radio. It has been ages since I have messed around with a car radio and everything has changed. What have some of you done? I thinking of something Bluetooth w/FM radio but I am not committed to that.

Well, I did exactly what I was afraid of. I broke the 4-gang power windows switch. You can see it in photo1 below. Also, I inadvertently removed my finger from a spring under one of the switches and sent it flying across my shop.

In photo2 you see the original bezel that came out of this car on the right and the switch on the left was in the trunk of the car when I brought it home. When I place this mystery switch assembly into the original bezel (photo3), it fits like a glove. Also, this switch assembly fits the Packard connector on the wire harness exactly (photo4). So, I get a second chance and will try not to break this other assembly.

The pins on a typical GM switch have a different pattern. I have no idea what this one is but I guess it could also be a Packard switch as well.

I stopped by the interior shop this morning. Starting to see some progress.

I need to disassemble all the power window switches and clean them up to make to functional again. Any tips would be appreciated. I would prefer not to screw them up and have to replace something.
