Ok, I cut the 12 volt plug off the end of the inverter cord. The cord is about 3' long and looks like black extension cord, no colored wires inside. One side of the cord has ridges down it. the other is smooth. Which side is the negative side? Looked on the net but couldn't find the answer. I'm quite sure an inverter has polarity. Also the stranded wire within the cord is quite skinny, looks like 16 gage. Should I cut the cord off nearer the inverter. This is the last wire I have to run.
