i got the exact same instructions with my trailtech regulator/rectifier, i am not running a battery however. i get the best light output with one yellow and the red hooked to the regulator, and the other yellow hooked to ground. with both yellow's hooked to power and the red grounded, the lights work but flicker or pulse while running. i just want to be sure this is correct/safe before i keep it this way. i have not tried calling eline, but i have left several emails to them as well a ricky stator with no replies.
