YAMAHA BX-1 / BX-5 Wiring Diagram

So I have a Yamaha Motion MB-III, and I want to change the electronics to something similar to the ones on the BX series.
(FYI, the pickups on Motion and BX basses are the same)

I did see a post asking the same question, but it seems to be dead.

The controls on the BX basses are : 2 volumes and a Tone pot with a push-pull coil split.

(Sorry if there's any errors in my English lol. It ain't my first language)

Here's the electronics in my MB-III btw (kinda weird that it has 50k pots. I feel the electronics were changed at some point):
