I am providing you with the positions of the Ignition Transformer Capacitors as it is a Coil on Plug engine Ignition.
They are numbered #1 and #2. The primary is #1 as it is on the right side, passenger side, of motor nearest the camshaft position sensor and timing is based of number 1 cylinder. There is not really a difference as you will see in wiring diagram, they are near bottom, and the designation for primary is because it is near the ignition timing components and the A and B designation is just a way to note which one is which.
Here is a video to help you see how to do the job.
Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
