I am working on a bike kit project I put together myself. So far things have going okay, but the 36V 10AH Headway LiFePO4 Battery 38120 E Bike Battery Pack has a different output connector. It’s a 4 Pin male Cannon plug, the 1,2 pins are neg. ,the 3,4, are plus. I do have the female connector but it is not wire on the system. My question is what kind of clamps(or do I solder) do I need for the two bare wires hanging from the wiring harness, and does that mean all have to do is find the right wire (+or-) to put to the 1,2, and the other to the 3,4. I had seen pictures online with similar products with only two going in the female 4 pin connector. But no diagrams to actually see how it’s wired up. Can anyone advise on this
