Replaced Cracked iPhone Screen Myself, Now Flashlight and Flash Won't Work?

I replaced my shattered iPhone 6 screen myself with no problems. Speaker, camera in both directions and perimeter sensor all work fine. The only problem is my flash and flashlight will not work at all. I have restored my phone to no avail. Can anyone identify the points where the flashlight needed to be reconnected? Or have insight on what went wrong and how I can fix it? I'm hoping I simply forgot to connect something, instead of having to buy a whole new part. If you think it's the part, will you link a replacement part? Thanks so much in advanced!

Best Regards,
