Tex-Mex Pup identification and wiring diagram.

[Pier Calacino]

Hello all,

I need some help please.
I bought a Strat in pieces, and it is suppose to have Tex-Mex pickups ? well, how do you ID them and which one goes where ?

One pickup has a white and black wire.
One has a red and black wire.
The other has a Yellow and black wire.

Does the color of wire determine that these are Tex-Mex pickups ? And which one goes in the neck, middle and bridge location ?

Thanks for any help.
