Yamaha pickups wires

[apo83]

Hello,
I have decided to rewire my first electric yamaha guitar .

This guitar has 2 humbuckers and one single coil pickup.

I have not kept any notes when I desoldered them because there was a mess, so I could wire all of them from the start (I am planning to chance the pots and switch also).

I want to have the humbuckers coil-splitted on the possisions 2 and 4 like the way it worked originally.

I now see the wires that come out from the pickups and get a little bit confused. The humbuckers has two coloured wires and one ground (bare). How am I supposed to tell how am I gonna solder them into pots and switch?

My theory is that the two coloured wires are the hot for each of the coils (north and south) and that the bare wire works for both. Am I right?

Thanx

Since the guitar previously had the coil splits, most likley is that bare goes to ground, one of the wires is the hot, for when it is operating like a normal humbucker (both coils in series), and the other is at the connection between the two coils. If thats true, then this second wire would get grounded to shunt one coil to ground in coil split mode.

Maybe you can do some tests holding the wires onto a jack cord and listen as you hold it up to a vibrating string. Better yet, measure resistance with a multimeter to test what is connected to what.
cheers

yes after some more search I am planning to check the wires with my multimeter...

If this is true on which lug should I solder that second wire on the 5-way switch?
Note: my guitar has 1 vol & 1 tone pots.
