This is a pretty common mod and various diagrams by Fender and others are on the internet.
As far as I can determine, it is not OEM but always aftermarket. If this is not correct, we can move it to the OEM diagram section.
Because the switching uses a series connection, the wiring follows a bit of circuitous route in position 4 and as the "wiper" action is fairly hidden in relation to how it passes over the lugs, my redrawing of this traces the internal connections too (bottom of diagram). This additional info may be useful in case you have miswiring and need to troubleshoot, or just like to know the underpinning of the connections visually.
The only other thing to point out is that the 4-way Oak Grigsby switch has a lot of throw going from position 1 to 4. You will likely need to enlarge the slot (on pickguard or Tele plate) so the switch cleanly enters each position without the lever hanging up just shy of the right electrical wiper connection. Clicking into place is not enough (and I found that out the hard way). You need the exact electrical connection and that is often past the click! A small file will take care of the issue in less than 5 minutes, so save yourself grief later on in the project.
The mod should work fine with Teles (just redo the cover connection on the neck pickup so it has its own ground, and that would apply to any other SC pickup with a metal cover as well) and most any 2 pickup single coil guitar. I've done this mod using lipstick pickups, P-90s, and humbucker size P-90s.
