What is the function of the short piece of wire soldered to the catalytic converter on a late model Tercel?

Answer 1

ok, this was my question, but no one answered it so I figured it out myself. Apparently, the OEM exhaust system for Tercels does not have this wire, so my theory that it was a grounding wire of some sort was debunked. The parts guy did not have a clue either, and then it dawned on me that this welded wire connected to a hook on an unused bracket post has the sole function of temporarily holding up the rest of the exhaust system while its being assembled/disassembled. Hope this helps someone.
