So I was trying to wire up my reverse lights since I just did a manual swap a couple months ago and was following an article on how to wire them up using the existing harness on the car, which is located in the drivers side kick panel. So I cut a yellow wire and a green/black wire(supposedly the reverse wires) and I couldn't get it to work so I connected the wires back to how they were, but now my fuel gauge stays below empty, even though there is a full tank. I've checked to make sure the wires were connected back together securely and also the fuse.
