There are tiny little + and - under the colored tape I guess that is, maybe I can test them with the dmm if I pull off the tape.

not with dmm, only led tester or any other v source because they are group could have 6-8 led in each.. each socket all group share the same + the dark wire you can feed each socket from the other end of the cable. so no need to pull off the tape

if you are going to use DMM must be direct on each led on the strip
