All the blacks go together, and the reds and blue go together. You can remove the cover from the mag, where those wire go, and snip off the white wire right at the coil. it's not needed and doesn't do anything meaningful.
With the cover off, it gives you an opportunity to inspect inside for ground up metal or metal dust and mag and coil, alignment.
I seem to remember on an earlier engine kit I had the wires from the kill switch being of many colors. 1 was green/yellow and the other was 2 different greens. Now when you have a blue, black, and white coming from the engine things get confusing real fast. It's a good thing it wasn't my first rodeo.
