Will this pair well with model KMMBT31BU?

I am not a professional, but I have worked with home, car, and venue audio for over 25 years. I say they will make a great pair. If that head end has the features you want, then this little amp will give 100w max watts per channel over the 50w onboard. It can pump out a very reasonable volume level with plenty left over so that the sound doesn't get distorted. In fact, I wouldn't recommend getting anything more powerful unless you replace the speakers too.

Does it come with the harness pigtails?

Yes and the RCA cables. Pretty complete. You will need a y connector on the RCA input side if you want to bridge the amp.
