A-ha, see it now. Green wire to 8uF, blue and red to 12 and 16 uF respectively.
If I understand the schematic right the negatives of both 21A Red and 21B Blue go together to the yellow wire. Please correct me if I am wrong
Look like the negative of the red is going between the 28 and 26 ohm candohm and the blue is tied to the 780 ohm? which is before the 268 ohm but the schematic is too blurry.
But yes the the both negatives are going to yellow but must be wired correctly per the schematic.
