Fuel Gauge Wiring Im running a ls1/t56 in my 86 iroc and am trying to get my fuel gauge working. Im running a 98 TA gauge cluster, and a 01 Z28 fuel tank. My wiring harness has been repined for a 99-02 PCM, so Im running a 99 PCM.
On the 98's the fuel level sender goes to the blue PCM connector pin 10, then from the red PCM connector pin 36 to the fuel level gauge.
On 99+ the red pcm connector pin 54 is the fuel level signal, and Im guessing the fuel level gauge goes to a serial data wire.
Ive got the gauge wired to the fuel level sensor atm and its not working, unless im on the wrong wire. How can I get my fuel level gauge working?

You need to do a express van segment swap or get somebody with Tunercat to set up the gauge. The 98 cluster is a direct wiring for the fuel gauge. You need to have. If you wire it direct you will only have the gauge with no evap control which you may not have anyway. Either way the nice thing about the gauge going through the PCM is that you can get the accuracy of the tank down. Try CalEditor or I have somebody that can program the PCM for you if you pm me.

Ive got it wired up direct at the moment, but its not working. Key on it goes to empty. Key off its at a 1/4 tank which is what I think Ive got, but I think thats coincidence.
