95 Ford Ranger gas hand stays on full after installing pump assembly. Intermediately worked before install. Doe's gauge need calibrating?

I had a fuel gauge problem it only worked every now and then it was a disconnected wire at sending unit causing the problem. The problem is before I found this out I started at the slosh module bypassing it this didn't solve the problem. I next replaced the sending unit assembly this is when I found the loose wire. After installing the unit the gauge now pegs past full I removed the bypass from slosh module and it pegged past empty, when I reinstalled the slosh module it pegged past full again. Should I try re-calibrating the gauge or something else? Gas hand slightly moves when ignition is turned on.

What caused my truck to randomly start smoking/burning near the headlight housing?

My truck randomly started smoking when i turned on my headlights, so i pulled over and popped the hood and a "burnt plastic" smelling smoke was coming from behind the headlight, i turned everything off and took out my keys but it kept smoking and was about to catch fire, it was alot of smoke, so i yanked off the battery cable and it stopped. Luckily i saved my truck from a blaze but i want to fix the problem myself if possible, the truck is a 2000 ford ranger, regular lights (no daytime auto lights) but the lights won't turn off at all, they are very dim and kind of flicker, and the highbeam dashlight symbol is also stuck on, any ideas?
