Yup, it’s just a standard import switch. But, when I wire the hot lead from the neck HB to #1, the pickup doesn’t work in the neck-only position. It seems to work when I connect it to the 3rd lug from the top which I’ve marked as #2. This is my first pickup change so forgive me if I seem a bit daft. It’s the different number of wires that threw me off.
No worries... To clarify, the wiring schemes I gave you would have to be followed completely, meaning you'd have to rewire the switch to follow what I've written exactly. If you just run the hot from the neck HB to (1) with the rest left as is, it wouldn't make any sound because the common from that side (4) isn't connected to anything. It would also kill your neck HB in position 4 because it would short it to the ground wire connected to (2).
Here’s the standard wiring diagram for my switch. As you can see, my SD ‘59 is missing the red wire in the diagram that used to be attached to the lug at the end. #1 in my photo.

That diagram splits the HB coils in positions 2 and 4. So, it isn't the same switch setup as the one I mentioned above.
Which setup are you after? The one I wrote above:
1 - BridgeHB
2 - Bridge HB + Middle
3 - Middle
4 - Middle + Neck HB
5 - Neck HB
That would need the switch rewired as in either of the two suggestions I made in my last post.
Or the one in the diagram?
1 - Bridge HB
2 - Bridge HB (split coil) + Middle
3 - Middle
4 - Middle + Neck HB (split coil)
5 - Neck HB
...which is not possible because you can't split the neck HB. You can still split the bridge though. Do you still want the bridge HB to be split in the 2nd position?
