I've read others have had success without the gateway, it was just the way I decided to do it. My boat does not have command link gauges. To get the trim gauges to be functional on the 7012 display, I had to connect the pink wire in the forward / right area of each motor, it was disconnected from the factory on my motors, the bullet connectors are already there you just simply plug them together and it feeds via the NMEA connection. Good luck.
