Look at picture #3. The + (12v) wire is the red and is shielded. The ground is the black wire and exposed. Agreed? Now Battery Tender has those same connectors. And here is the catch. To connect to a battery with their pig tail, they have to reverse the wire polarity when joining the two connectors together. So that Red (+12v) is the shielded portion on one connector and its the un-shielded part on the mating connector. That keeps Red to Red and ground to ground. The sides of the plug recepticle pic 1 is ground and the center portion at the bottom is the + connection. Make sure that the center portion is connected to +12v and the side is connected to Gnd. You probably know all this anyway so this may be redundant. Isaac
