Ok,
Resetting codes, took off the Negative battery lead.... BUT, when I went to tighten it back on, the threaded part snapped, so, I cannot properly tighten the negative battery lead. So 2 things,

1. Is there a way to Jimmy this until I can solve the issue, I dont want the lead coming off while driving.
2. Is this a hard part to find, I can't even find the name for it, its just a bolt really, it seems to me.

 

battery terminal is what your after

Pick up a new terminal and if there is enough cable you can swap in the new and move on with life. The bolt on style should make it pretty easy to do, you can strip the wire with a razor blade if you need.
