Agreed but that is what all the E90 people seem to do. Most is just a fiber loop and all the components in the pic above are fibered in series. The connector simply has + and - 12vdc and has the in and out fiber.

I took some things apart last night and found where the black connector hooks to the splitter (a cable removed from the top silver box in the pic above). Now I am not sure where the yellow one hooks on. I assumed incorrectly that it would go where the black one was removed. I thought the splitter split the signal between the old and HD tuners but that may not be correct.
