DJenner8 - I think I figured out the CAT6 issue. I ran a CAT6 cable from the cab of my truck back into my camper to locate the head unit of my KG-1000G in the camper while at camp. So the CAT6 wires need to be "crossed" on one end of the cable. In particular wire 5 & 7 need to cross. ALSO super important. When you go to slide wires into the RJ45 pass-thru connector, you need to rotate the connector 180-degrees. So if the (clip) is on top on End-1 the (clip) needs to be on the bottom on End-2.
