I've read through this thread and I'm scratching my head. I'm going to echo a bunch of other people here. You are
literally describing a non-premium TRD OR.
Just buy one of them. No push-button. (Only premium models have it) Lever-actuated 4wd. Locker. AND you're not trying to figure out electronics and making things jive.
Don't like CRAWL? Don't use it.
Don't like the scoop? Swap it with someone who does. There are plenty who do. Or just buy a new hood.
Want the two-tone SR5 cloth interior? Swap it in.
You obviously have the money and knowledge to do these things, but to buy a standard SR5 and start mechanically tearing it apart to make it into a TRDOR is, IMO, stupid. Your time is money as well and you've admitted yourself that your electrical knowledge on these newer vehicles is "light"
Unless you just want to do this so you can create a "look what I did" thread?
