Did you want the pup in series or parallel?
I think for series you want to connect black from coil 1 to green from coil 2.
Then red is hot and remaining black (and bare) are ground.
For parallel, you twist coil 1 red and coil 2 black together, and they are hot, and coil 1 black and coil 2 green together, and they are ground. (as well as bare ground wire.)
(I tried red and green together as hot, and both blacks together as ground for parallel wiring, and they were out of phase.)
I wound up just using one coil because I liked the sound better. More of a P-bass tone.
If you have the time, try all your options with a dummy output jack and some aligator clips and see what you like best.
