Review on 14 Gauge SAE Plug 2 Pin Quick Connect Disconnect Solar Extension Cable For RV Motorcycle Battery Trolling Motor Solar Panel by David Lambert

As others have notes within the review section, the polarity is flipped (Black is Red, Red is Black) in the way they wired it to the plug. The "female” part of an SAE is always the Positive, and the "Male” the Negative—with this product just check to make sure your wire colors aren’t flipped to the reserve. Alternatively, you "can” pick up an SAE adapter to reverse polarity, but that’s… lazy, and can lead to issues down the road—especially if said adapter isn’t attached when it needs to be.I completely wired my truck all the way to the bed, and thankfully left enough slack to modify it if I ever needed to. I tested the leads at every point and when I attached the SAE connector I never thought to check the polarity.Just save yourself some time and make sure it’s setup correctly.Other than that, it’s well made, and had plenty of cable (which I trimmed) for most under hood tasks.(Pictured: Modified plug; the red wire should have been black, and the black should have been red)
