the 22re in my 1985 4runner is tired. I bought a 1988 4x4 pickup with a 1994 22re in it. I want to put this engine in my 4runner. Is there something different on the wiring or fuel injection between 1985-1987 and 1988-1994 because I have been seeing there are computer chips on ebay for the 1988-1994 22re. but not the earlier ones. I would like to put this later engine in my 4runner and still be able to put one of the chips on it. I am trying to see what will have to be done to put this engine in the 1985 4runner. Thanks
