The point of that above post is that you can buy that combo switch for like 25 bucks and either get it to work as is ( i think theres a slight wiring difference in the wiper since its got the dumb mist function) or just unscrew your guts from your current combo switch and slap it into the housing. Theres no need to spend a ton of money on a used combo switch or a reman one. Its super cheap and it works.
Couple of things. If you transfer over your turn signal stalk, there is a small ball bearing in the end of it under spring pressure so when you take it out, dont let it fly out, also the little metal bracket thing that gives you grooves for pushing in your high beam stalk is different between the two so youll just use your old one. Also the hazard indicatior is printed on the wrong side but whatever

The new turn signal stalk uses a pressed pin that you can just drill out and then reuse the threaded screw to attach your old one to it. Or just use the new setup.
Ive taken these things apart so many times and messed with them so much my original one cracked and this was a super easy way to refresh it to new. Ive seensome of these go for a ton of money online and used and theres just no need
