Just went to the dealer and got me the knock sensor and the wire, it seem that the part # listed is incorrect or if I was looking at certain year model so I like to address that the knock sensor part # is 89615 -50010 and the wire part # is 82219 - 35010, this is toward to the 1992 4runner, I don't know if it will be the same as those 89 to 91 but I believe it will fit most of those 2nd generation 4runner.

I'm associated with an auto supply company, if you need anything just PM me I would gladly get it for you at a low price.
