I just found out it wasn't my fault.

I didn't blow a fuse, relay, or shorted out the battery of the Toyota Forerunner when I arced the battery(on accident). The fact our area manager told my coworker to take out the air filter housing, he unknowingly unplugged some of the electrical wiring that regulates the air flow.

So, all of that drama and the customer giving me the stink eye was unnecessary!
