Can someone tell me where this ground wire goes? I can't find anything on it. Need to know how easy it is to replace. I'm having all sort of problems with my electronics and I hope this is the cause. Or a fuse.

The wire itself isn't issue it's the point of attachment. It would be way easier to just cut those ring terminals off and put on new ones. Then sand that area back down to bare metal and put a new bolt in it.

 

So would this be causing my electrical issues do you think? My dash, radio, window controls, chair controls and a few other systems cut out. But come back on when I hit my brakes. There's sometimes a popping or clicking noise from my fuse box when it happens.

 

It does sound like you've got a little electrical gremlin here which very well could be because of a bad ground. Do they just cut out at complete random and then come back on when the brake is pressed? Have you looked around the brake pedal for a pinched wire or something along those lines?

 

Everything is fine when I start my truck, as soon as I accelerate everything cuts out. My blinkers and lights still work though. They don't always turn back on when I hit the brake, but when they do there's all kinds of noises coming from truck. Then as soon as I accelerate, it all goes away again. Ive had dash issues for a couple years where the gauges would reset, but the truck is almost 20 years old so I didn't think anything of it.

 

I'm wondering if you've got some loose wires under the dash being hit by the pedals. Otherwise cleaning up that ground is a great start for sure.

 

Definitely going to clean it up, and I'll look under the dash tomorrow at some point. Thank you

 

Yes, your electrical gremlins are due to the rotted ground connection. Pretty common problem as this generation of truck ages and experiences body rot.

Install new terminal rings on the wires and re-attach the ground higher up so it has more time before the cancer reaches it again.
