I have a missing cap on an unidentified outlet on the assembly for my rear brake caliper. Does anyone know what the part number is for this missing piece or what it is called?

This image shows the passenger side where the cap is located:

dunno the part number but it's just a brake bleeder dust cover
I think you should be able to get one in the HELP! section at most auto stores

 

[WTF_LOL]

as was already stated it is just a cover for keeping dirt out the bleeder. I have seen them at auto parts stores near the brake bleeding tools.

YOu can even get them in red to match you lines

Which is most probably how it was lost, when the red hoses were installed.
