Not sure if you were able to get this resolved already but I spoke with Paul at Max-Gains Systems, Inc out in Georgia and he was very knowledgeable. I had a similar issue with the main coaxial cable connector having to be replaced and he suggested buying these 3 pieces to create a new piece which will allow you to connect the coaxial cable end and the auxiliary connector near the trucks 7 pin so you can utilize your trailer’s camera/invisible camera set-up. I just ordered the parts today and he said this would solve my issue, so I’m taking his word and giving it a shot once those pieces come in. He also suggested using electrical tape once all those 3 pieces are connected together, so it looks like one solid piece. Hopefully this helps out anyone out there experiencing a similar issue.
