Glad to hear that your dash bezel turned out nice.
For the gas sender wires, there's a tan wire and black wire coming off of the fuel sender unit on top of the tank. Of course you can't access the wires where they connect to the sender unit without dropping the tank. But, the black wire screws to the rear frame rail for the ground, and could be a dirty, rusty connection there. The tan wire plugs into a small round black connector mounted on the rear frame rail, underneath where the gas filler neck is. You'll have to get on the ground and look up at the rear frame rail to see both those wires.
The connector that the tan wire is plugged into has a pink wire. So, the tan wire connects to pink. From there, the pink wire goes into the wire harness that is inside the trunk. The pink wire can be accessed at the big, flat, black harness connector that's in the left upper front corner of the trunk. So, that's 2 places you can test the sender wire, at the "tan-to-pink" connector under the filler neck, and inside the trunk, the pink wire at the harness connector.
The lights/wiper letters are white.
If you haven't thought of it, it's a good idea to change out all the old rubber fuel hose connections with new fuel hose at the tank and the front end of the fuel lines. The ethanol in the fuel damages the old original hose material, so it can eventually crack and leak. New fuel hose is ethanol resistant.
