I apologize in advance for the long post. So, I swapped out the old TVs on my 2003 Signature with smart TVs, so I can connect with the internet just fine. The problem is that I can't use any antenna or cable hookups from a pedestal. The old/original setup had everything connected with the composite cables (red, white, yellow) coming from an a/v controller in the front cabinet. The coax from the antenna and cable hookup in the bay goes to the amplifier in the cabinet above the driver seat. Evidently the two inputs (antenna and bay cable) merge somewhere, because only one input goes to the amplifier. Then there are two other coax cables coming off the amplifier, one says TV and one says AUX. The Monaco owner book says antenna/cable works through the old VCR, which had a coax into the ANT port; from there composite cabling went to a switcher, and from there a whole spaghetti mess of wires went all over, including the Bose up there near it. I mistakenly thought that since the manual said everything went through the VCR, the coax cable that was connected to it would be the one from the ANT port on the amplifier. Well, it doesn't. In fact using a tone tracer starting with the amplifier end of the coax that was connected to TV port, none of the three coax ends in that a/v cabinet are the other end. My next step would be to trace the AUX cable to see if any of the cabinet ends are it. Frustration. So I guess the question to the group is: has anyone with a similar original setup redone their cabling, and can you please tell me which cables/wires run where? As mentioned, my goal is to be able to use the cable from pedestal, or antenna on roof, to the front and bedroom TVs. I'll figure out the Bose sound stuff later. By the way, the wiring schematics in the large wiring book are useless for this. Thanks in advance.
