Trying hard not to @#$% people's cars up

Aw geez. Yesterday, today, and tomorrow is training on how to install those "blow and go" units on cars of people who had two drunk driving convictions. Yesterday went, well... okay. After today's, there is no freaking way I'm going to do this. Today's install was done pretty much by myself, and the unit did not power on. No biggie. The worst thing is the previous person who worked there stole all the sockets and extenders, and the flashlight. Without the right equipment, it's a nightmare. Ended up I didn't attach some of the wiring to a good ground. The only way a good ground could be utilized was to have an extenter and attach the wire elsewhere. This guy that's supposed to be training me is real nice and everything, but he's the most high-strung person I've met in my life. So he jumped in and tries getting another good power connection instead of just finding a better ground. The worst thing that could happen, did. He cut the airbag wire. They didn't deploy, but had had to rig a jumper in there too. Oh yeah, without those socket extenders, we can't pull off dashboard panels and plates to give ourselves room to work. So we are working pulling wires through a two inch opening. It sucked. So after watching how easily you can mess someone's stuff up, there's no way I want any part of it. I feel bad because this guy drove 4 hours to train me. But he also came here with the assumption I had three months of wiring instruction. I didn't tell anybody any such thing. When I told the guy I had no experience whatsoever, I think Mr. Type A shit his pants.
