The part number you listed is for just the transmitter, not the entire kit that includes the receiver. That, and the fact you list a 2012 CVO Ultra in your profile, makes me guess you already had the receiver for the CUSE and you're trying to add the Softail Convertible. If I can make that assumption, and if your GDO works properly with the CUSE, then the problem would most likely be in the wiring of the transmitter to the Convertible. Does the transmitter LED light up when you flip the high beam switch with the ignition on?
Depending on how old the kit was that you bought, it may not have had the correct installation instructions. The latest version has separate instructions for 2011 and later Softails with HDLAN, while of course earlier versions did not. If your Convertible is a 2010 the old instructions would still apply, but if it's a 2011 or later you need the latest instructions. This note is from the latest version: "2011 and later Softail models will require separate purchase of an Electrical Connection Harness (Part No. 72673-11)."
There is a troubleshooting section near the end of the instructions that came with the transmitter.
