ok guys i need some question answered if anyone can help..
i have a 95 sc400 that i am doing some things with and have reached some areas that are alittle hard to find answers in the seach sections...
so here they go
do the abs wheel sensors control speedo?

and my other question is on 02 sensors..do i really need them,or can i use some sort of computer,or resistors to fool the ecu..how does this control fuel&air is what i am tring to understand..

alt.relocate bracket,has anyone used this,?

on here somewhere in my hours of searching i found someone who said that you can use a ls400 fan pulley to delete the hydro fan on my car,is this true,and from what year ?

i will have alot more questions i am sure..any help would be great..i have been looking at this thing torn apart so long that i am going build blind,so the answers are probly right in front of my eyes,but you know..i need help...thanks
