Re: Dual tank wiring
Yes.
You should have two wires leading from the fuel tank sending unit. One of the wires is the Ground wire and may already be grounded to the frame (near the tank). The other wire is the signal wire and leads to the harness. It is this wire that leads to the fuel gauge. You'll need to locate the signal wire on the wiring harness and tap into this wire. (I'm not sure of the coloring code on a '77 fuel wiring harness.)

Re: Dual tank wiring
sending unit is blue on my truck, roughly 18 or 22 gauge, same as everything else on the truck.
