You've probably got a photo that's too large, so you'll need to resize it. No bigger than 1500 pixels on the longest side. Windows 10's default photo viewer has resizing as a right-click option. Choose custom size and whatever's the biggest dimension, type in 1500 pixels. There's also around a 1Mb size limit, but this isn't normally a problem, but if it is, just use a higher compression ratio/lower quality setting on the slider when saving. Otherwise use an external image hosting site and link to it using the image button. (Note that the default upload and host locally tick box needs to be cleared if the picture is bigger than the forum upload limits). A maximum width of 800 pixels seems to be best for fitting a remote hosted picture on the screen.

Your 3-way blade switch is equivalent to the one in the SD drawing, except that the terminals on one side have been moved round so that they are now in a line. The two middle terminals are the common terminals for each 'side' of the switch.

You'll find that in the SD picture, the pickup signal wires are taken to the common terminals of each side. So in your case, taking the '3-way switch' text in the SD pic as the nearest the neck end of the switch (just imagine it's 8 pins in a row, not 4+4) and the top pin as pin 1, you'd solder the bridge pickup signal wire to pin 4, the neck pickup signal wire to pin 5, and link pins 1,2 7 and 8 together and out to the volume pot. Pickup grounds get soldered to the back of the volume pot or the tone pot. So it's basically the same as the SD diagram, but with a different topographic arrangement.

What the SD diagram doesn't show is that the backs of the volume and tone pots need a soldered link between them or the circuit won't work.

As you have noted, for the SD 59, the signal wire is black and the green and screen wires get soldered to ground. For the DiMarzio, the signal wire is red and the green and screen wires get soldered to ground. The remaining pairs of wires are probably already soldered and taped together.
