Hello I was working on my 2001 chevy blazer and was wondering where this grounding strap went and what it was. Thank you

 

That photo is really really blurry, where is this located, year make model will also help.

 

It won't allow me to add more photos but it comes from the gas filler cap and leads down but do not where it attaches to. It looks like it attaches to a module that is a attached to the rear cross member between the gas tank and rear bumper. If that will Help.

 

It is also a 2001 4 door 4 wheel drive chevy blazer

 

If it's coming from the fuel filler then it should ground to the cross member above the rear axle. I believe it's to reduce the chance of spark from static electricity.

 

Yes that is what it was. I fixed it and regrounded it. Thank you!
