Quadratec LED tail light issues

Need some tech advice! I have installed a set of LED tail lights on my 2001 TJ. Bought them at Quadratec; Quadratec® LED Tail Light Kit for 01-06 Jeep® Wrangler TJ & Unlimited - Quadratec. They work fine, with the exception being they are always dimly lit, even with the Jeep off. My cruise control does not work now (like the Jeep system thinks the brake lights or hazard lights are on). Also, if I turn on my hazard lights with the Jeep ignition OFF, my dash lights behind my temperature controls come on every time the tail lights flash. I am using the Quadratec-supplied flasher relay (specifically for LEDs) and still have this issue. I have used a voltmeter to check the pigtail coming back to the tail lights and see that there is a constant 7.1 volts coming into the hot wire for the running/turn signal/brake lights. I would think that unless I have my foot on the brake or have my hazard lights on there should be NO voltage coming to the tail lights. Is this correct? I have done a search online and found the exact same "low glow" issue some people have with aftermarket LEDs on various vehicles and their fix is always to add a resistor to the hot wire to use up the constant low voltage. But I wonder if that would simply be a Band-Aid over another problem. I have contacted Quadratec and their only advice was to make sure the bolts that attached the taillights to the tub of the Jeep are clean because that is where the taillight assembly is grounded. I have done that and there is no change. Any suggestions?
