Which one of these videos is correct ?

Two totally different videos for the same thing…. One is pretty straightforward, while the other one it looks like the guy is taking half of his truck apart….

Just based on the thumbnails and titles, the first video is showing a 2nd gen that has all the necessary pre-wiring installed by Toyota during manufacturing. Second video is a 3rd gen that does not have the factory wiring options which is why it's a ton more work.

To find out which one applies to you, you'll have to crawl under and look for the necessary wires or start taking things apart and see if you won the lottery. 50/50 chance, good luck.
