You need to develop your search techniques as most ground has been covered on this forum many times and at least the basics can be found pretty easily.
Drop into Google: fj80 remove alarm disable site:ih8mud.com
Drop into Google: fj80 power steering replace site:ih8mud.com
Adjust those search strings as you learn more. You'll have to learn how to skip the fzj80 stuff, etc. and you'll learn which posters are most reliable, etc. After covering the basics via search you can ask questions that fill in the gaps and help make mud an even more complete resource moving forward, etc.
