Daytime Running Lights

I understand the '06 Fusion is pre-wired for DRLs. Actually, they're a 'fleet' option. I tried to find the OEM relay that would turn on the DRLs and was given two part numbers by Ford ... FOAZ-14N089-A and F5TZ-14N089-B. They aren't that expensive. My inclination is to get both and try 'em; but, I don't want to fry the computer. Any suggestions?
