    First time posting, and been searching like crazy on the forums and most threads seem to be out of date with no links to pictures, so asking once again. I was changing the o2 sensors on my 95 gsx and notices this ground strap wrapped around the rubber mounting after the Catalytic Converter. the other end was broken off.

    My Question is what is this ground strap for and where should the other end connect to? Adding a picture for reference.

    Thanks!! IMG_0564.jpg

    That wire strap is to ground out any static charge buildup on the exhaust pipe but is not essential to normal car operation. {It does not provide a ground for the rear O2 as some say - that O2 has it's own grounds in its harness plug.} The wire strap attaches to the catalytic convertor heat shield (looks like you might have a hole in the lip on yours for it).

    To further add, both those straps are for your audio system. It cancels out the noise produced from the exhaust.

    Thanks all, I dug through the electrical Service manual and found its technically called a "earth cable" I tapped it to the cat's heat shield. Added a picture for anyone with the same question in the future as well.
