2004 Workhorse Chassis Ignition Problems...and then some

I had a viewer from Long Beach contact me about replacing his roof on a 2004 Winnebago Sightseer. We scheduled a time and location for him to drive from California to drop it off, but he was late..quite late. After calling him a few times, his motorhome showed up on a tow truck because the engine would not stay running. Surprisingly he was in very good spirits about the whole ordeal and gave me a walk-thru of all the custom changes he has made to it. It is obvious that he cares deeply about his Sightseer and I feel grateful he would trust my shop with it just from a couple YouTube videos. So before I can replace his roof, I have to get the motor home running. Here is a quick rundown of the ignition switch replacement.
Thanks!
