Ran a 1.5 Ft HDMI cable from the TV to this HDMI female-female adapter. This way the xbox can plug in to the built-in TV or a different one.
Finally finished. The whole process (including waiting for the T.V. to ship) was about 2 weeks. There was a lot of things I had originally intended on doing that I wasn't able to unfortunately. My biggest regret is doing this for my friend instead of myself.. As payment, he gave me the Dremel he bought for me to use on the project, so I suppose it worked out in the end
