fuel gauge ? not sure how newbie this is but i just finished a 99+ pcm upgrade on my car and the only issue i have left is the fuel gauge. I am reading 24x ohms on the sensor wire from the fuel tank with a full tank of gas. If i connect that wire to the fuel guage output wire from the pcm the gauge reads empty like i just put the output wire right to ground. So my question is if the pcm internally steps the ohms reading down to a different value that the gauge can understand?
