fuel sending unit and fuel gauge trouble

ok guys so i crawled under there with the flash light and looks like there are no wires hooked up to the fuel gauge or the temp gauge... i found a wiring diagram online...looks like a wire comes off the voltage limiter, goes to one side of the fuel guage, and the other side takes the blue wire that goes to the sender, that should be pretty basic to do?
you got a wiring diagram ?
