I checked out my wiring this morning and it's slightly different than yours.

However, since it appears from your picture that your new harness is in place, and you can connect CA and PDC using the old harness, can't you just ignore the CA wiring in the new harness?

I assume the reason they provide CA in the new harness is for those vehicles where PDC and CA are routed separately, through separate holes, to allow the new harness to be installed through the CA hole.
