Fuel/Water Temp Gauge Issue Found! Now what...

Roy Worrell said
okay so I am going to ask another dumb question.... I grounded the sender wire and no movement from the gauge. i have an extra cluster so i plan on swapping and seeing what happens. my question is that there are no wires going to the lugs on the fuel gauge so are there supposed to be? or does it get everything through the circuit board?

In the picture here, the wire harness plugs into where I've circled in yellow. The studs for the gauge make contact to the copper traces through the nuts that secure it to the board - circled in red. So, to answer your question, no wires go to the lugs on the gauge.
