Cigarette port
I had the same issues with the wires. But tried my best to hide the wires and then tucked whatever I was able to.
And then those clips after holding in the spot where I wanted the clips to be, i let it sit for a bit without any wire inside and they seemed to stay put, together with some zip ties.
And for the cars I didn't want any wires showing I bought a $10 Hardwire kit and hid all the wires. Worth every penny and freed up my ports.
