How were you testing this without a trailer?
I installed mine, and don't have a trailer to test with -- I get no lights, unless I double click on the knob, which brings about the pulsing blue glow you were referring to. I can't get it to do anything else.
Borrowed one of these….

It makes the truck think there is a trailer attached. If you are getting the pulsing blue light, in all likelihood you are good to go.

all it does is light LED's when actions are taken (e.g. press brake pedal, turn on indicator, enter reverse)

That's it
