Hey guys, I'm new to the forum. I have a set of DDM 55 watt 6K low beam and high beams. I used an extra wiring harness i had laying around and connected my Low Beams and they would not work when polarity was reversed, but they work when the polarity is positive. The harness has a built in 40 amp relay. Now the issue I'm having is that I have a CEL on now. But my concern is why is it that these trucks are reverse polarity but mine work when its positive polarity? Will error eliminators fix this issue? Will i need to connect the eliminators reverse polarity? Is it safe to run low beams until error eliminators come in from DDM in 2 weeks? And as for high beams, will I need error eliminators/wiring harness for those to work properly,(reversed polarity also?). As of right now my high beams do not work at all. Thanks for any info.
