How to install auxiliary wires in TRD Off Road without preexisting buttons

[Nageeb]

Hi! I just got my first Tacoma yesterday: it’s a TRD Off-road and I love it. It’s the standard trim for it so where auxiliary buttons would be, I have blank plastic inserts. If I want to add wires to hook up lights and other equipment, how would I be able to do this and what do you recommend? If you have a great video guide that would be amazing. Thanks!
