Wiring gas tank <br />I have a aluminum gas tank with a fuel gauge built in. The problem is the wires they not connected<br />The gauge that in the tank only has two connections to it. One is for ground I think the other is for that is my question do just connect the other one to my fuel meter then to power. I have not looked at how the wiring is done on my meter yet. But I guess I find which one was the giving it power and which one went to gas tank gauge. And see that works.<br /><br />Also for the ground I going ground to the ground on my engine is that good. Our do I use the negative on the battery or both I think will be ok if not let me know.<br /><br />If any one know how to just wire a to my gas tank gauge and to my meter which tell me how much fuel I have with a simple switch to turn on when I want check it. Might help
