Good luck. Many OEM parts for CR-Zs are becoming unobtanium. Simple question was your car a Base at Birth or was it an EX or EX with navigation. Even simpler, does your light stalk have the fog light switch? If it was an EX or better, than everything maybe there. If it was a base, and you get lucky, you may be able to piece together a working solution using good wiring techniques and non OEM parts.
Mine is an EX and I do appreciate the fact it has fog lights. Will be better when my lighting upgrades are complete and all are same color temperature.
Talking to a dealer in person, they may be able to save you some money and get you just the parts you are missing.
