I bout a rebuilt 2008 f150 King Ranch, while I was replacing the battery I saw someone had removed the boot from the passenger side firewall and it looks like they shredded a wire.... its green with a black stripe, looks like it may come off the ECM... truck runs and no engine lights... should I be concerned? Should I just leave it? I don't wanna pull the loom of I don't have to but I need to know what it's for....
