Need some help asap
 

Okay I'm not sure really what the part is called but will try my best to tell you what it is.

Under the battery, Under the carriage that holds that, I had to replace my 175 fuse on my 2003 blazer, Noticed when doing it the line that hooks to that to I do believe the alt it was spliced, Was damaged so badly that I had to rig it up very poorly just to have power to get to work this week. Does anyone know what that line is called? I do believe it might be called a fuseable line or something along that term? But I need to know where I can get a replacement asap, Thank you for the help :)
