I just started getting into fixing up Go Karts for my grand kids. I purchased a used Yerfdog Spiderbox 150cc. (at least that's what I was told) ? I was wondering if someone here could tell me what this is? I know its hooked into the brake linkage. It's located under the drivers seat. I'll attach a couple photos. I see the wires its connected to are exposed so I want to figure out what to do with them. I'm sure this seems pretty lame for most of you here. This is my first bigger go karts. Any help would be greatly appreciated. Thank you. Ed
