BTW, from the looks of the diagnostic information the 98 should work just like the 97 without the pcm connected since the ohms are the same. The 98 pcm has fuel level input, fuel level output and a 5v sensor return. If we only knew what the pcm signal was reading. Maybe you guys could hook the old pcm up and check ohms and voltage through the pcm and also with the input and output wires connected without the pcm.
