but I'm trying to do is so the green and black adapter that you showed on your video the male version well I'm getting the female version of that exact type of connector powered DC jack connector whatever it's called but the wire that I need to use is an 8 gauge wire and this only fits 16 and 12 gauge so I'm trying to figure out what kind of thing I can put at the end of the wire to reduce it I thought of using a a spade of some kind but what I only could find was these Burndy YA8CTC38 One Hole Hylug Code Conductor Long Barrel Uninsulated Copper Compression Terminal, #8 AWG, #8 Weld, 37/24, anyways I was thinking of that or they had these gold ones they're almost the same thing but instead of rectangle shape they're round shape all of them have a hole which I didn't want it with the hole but there's one with two holes and if I cut the one hole off there's enough space to trim it down to fit inside the power jack thing so I'm hoping that will work otherwise I'll have to solder 12 or 16 gauge wire at the end and just long enough to stick it into the power jack adapter
short answer: yes long answer: on the plug side: the center almost always the positive, on the cable side: the short leg almost always the positive, for cable itself, the unique one (stripped, colored, printed, etc.) almost always the positive. I say almost always because sometimes the opposite happens, either because of unintentional (wrong design) or intentional (special case design)

So the long leg on the female one is the negative?
