Good write up. I do all the methods depending on which one presents its self. I wired a '98 PCM to work with my '96 GP. Then I had to wire a '98 PCM to work with my '97 GT. Then wire in the fuel sender because I got a 98 dash and a 98 dash has a fuel gauge that must go through the PCM to work. So theeeen, I had to get a 98 sender for the tank…oh wiring is grand.
