I have scoured the internet over and still come up short when it comes to wiring for the fuel gauge in my '86 K-10.

I have found diagram after diagram on the wiring from the LH and RH fuel tanks to the selector switch.

What I am looking for is the path the wiring takes from the selector switch to the gauge it self. I have no continuity from the sending units to the gauge. So, my needle is pointing past fuel. I understand that if it was grounded out it would go to empty and that 88 ohms is the magic number for the FULL mark.

I have replace my selector switch. My truck is swapping from LH to RH and back just fine. I have checked the grounds on both tanks. But being that both tanks are not sending signal to the gauge.....It is my thought that the problem lays between the gauge and the tanks.

I appreciate any and all help!
