You are correct, Generation 3 uses RJ45 connectors and I have confirmed that everything must be shielded. While I am thinking about it, for others ....... I first tried a hole drill on the outside connection but had good success with a router blade for my Dremel, very easy. One other thing for those considering this. I want my Starlink to be powered by 12 V and there is now a relatively inexpensive device that means you don't have to cobble together different devices -- https://www.trioflatmount.com/shop/p/gen3-12vconversion, the company claims it used 4.5 amps. So, all my stuff is due today so I will see if I can get it to work, thanks for answering.
