This mount moves the Aux feeder to the top and is mounted using the screws for the top PTFE coupler mount. I recommend replacing all the couples and PTFE with a single piece of 3mm i.D. PTFE from feeder to hotend with no couplers.
To use! You will need a 8" or so 4 pin extension cable. The connector is a Molex Micro-Fit 3.0 dual row connector. Buy on Amazon The wire should be what you have that is appropriate. If you have can bus cable that might be better.
