My considerable paint skills at work:
Now to clarify, just use the small part of wiring that SHOULD come with your new speakers, and cut the factory end off of your original wiring. wire the + and - to the pioneers that you have and twist them together, then twist the (stripped) tweeter wires onto those. So you will have three wires joined together. Then solder and electric tape them. Then just mount the pioneer as the door speaker is originally, running the tweeter wire through the little hole. This will give you the same wiring as the factory did, the tweeter in parallel with the main feed. All should be well.
