make a clean cut across (seperating it, it's important it's a clean cut, i.e. all the seperate strands of wife inside are the same length, just use scissors)

take the cut end, and seperate the two wires by pulling them apart (might have to put a knife inbetween them to start the seperation... just do it at the very end... just so it's seperated like in the pic)

i imagine you don't have wire strippers so just use your teeth... bite down, about 1/4 inch from the end (do each wire seperately) and pull on the cord... you only wanna bite hard enough to peirce the rubber insulation (rubber around the actual wires) the pulling will fully seperate and pull off the uneeded insulation...

once both ends are exposed, just twist them a bit (doesn't gotta be much, just so it doens't come unraveled... like a half turn or less with your hands)

then you should just have to shove each end into that thing inbetween your fingers in that 2nd pic... (one wire goes in each hole)
