Could be totally wrong here, but it looks like, whats going on here is, there's an extra connector wired in, so you keep the yoke connector original. That extra two wire connector. That the green and yellow wires are shoved into. Are connected in parallel with the red and blue wires on the yoke, which is the horizontal coil.
The male yoke connector on the board, which had the yoke plug plugged into it originally. Has it's horizontal pins cut/disconnected from the chassis. So I would guess, you just plug the yoke back in as before and switch the yellow and green wires around on the smaller connector. No need to cut anything! Just an uneducated guess though
