I ever tell you the time I was putting air bags on my Brand new toyota 4 runner? I was running wires for the compressor, and decided to drill a hole in the rubber gromit holding the main wire loom . Well the drill slipped and tore the heck out of the wires, right at the firewall. On a brand new, week old Vehicle. I had to completely remove the harness from the vehicle to repair it. What a job!!! Learned a lesson there....
