Bridge with split neck in position 2, and split neck in position 3 (red & green coil active when split):
Standard Tele 4-way layout with parallel and series combinations, no splits:
While it's possible to do a lot of switching and splitting options just using 3, 4 and 5 way lever switches, I think the most flexible and usable layout is the above standard Tele 4-way layout in combination with an On/On/On mini-toggle. The 4-way lever switch allows you to combine the pickups in either parallel or series, and a mini-toggle will allow you to set the neck humbucker as either series, single coil, or parallel. For maximum flexibility with the easiest wiring, you just wire the toggle switch like below and then connect the + and - to the 4-way as shown in the diagram above.
Adding a mini-toggle to the standard 3-way wiring has the same effect, albeit without the series between pickups option.
Push/Pulls can also be used for series/parallel switching instead of a toggle switch, or even for phase switching if you want a scooped nasally sound when your pickups are combined. A push/pull is also an easy way to add coil splitting, as you can directly control which coil is active (let me know if you need a diagram for that).
