installing a fuel cell in the trunk of my regal and had a question. i noticed the sensor the cell came with has 2 connections on top. one has a G next to it which im guessing is a ground? does this go to the ground go to the black wire in the stock harness? does the signal wire for the stock gauge in the harness go to the other side of the fuel cells sensor? just looking to figure out what wires go where on this to get the stock guage working. thanks guys
