A few questions for Y'all

[NW_Ryker]

Today I finally got some work done on the truck. I'm slowly crossing things off my list to completion. But, I need some help. I have two questions.

Are replacement fan switches sold? My fan doesn't come on with the control, but does when jumped from the battery. If they do sell them, would it even be worth it to replace or just buy a whole new unit? Mines pretty beat up anyway.

I have an aftermarket tank in my truck, and the gas gauge doesn't work. The harness that plugs into the tank is pretty torn up and I'm guessing that's the culprit. I'm not sure if it's the original harness for it though. I'll snap some picks of it tomorrow, but for now I'll leave a link, and hope someone who also has one can give me some insight.

Thanks guys
