Hey Lee,
The Redarc Tow-Pro Liberty Brake Controller w/ Custom Harness # RED74CR isn't going to light up unless the trailer is connected or if you press in on the manual override control knob. It just turns itself off when not in use to conserve power. The harness you used isn't an issue and you should be good to go.
