Can anyone help me moterize the daytona sp3?

So I recently got it and I really want to try motorizing it but I’m honestly pretty lost. I’ve never done anything like this before, no experience with lego technic mods, motors, wiring, or anything like that. I’ve watched a bunch of youtube videos where people motorize it and make it rc, but none of them actually explain things clearly enough for a complete beginner. They just kind of show the process without properly breaking down what parts are being used, why they’re used and how...
