Re-wired the ignition switch today. I found the ULPower instructions to be confusing, so I left a message with Zenith asking about it. Roger called back on Friday (he had been on vacation) and set me straight. My wiring was about 80% correct based on my interpretation of the ULPower instructions - or 100% wrong if I'd tried to use the switch wired the way I wired it. It's all good now.
I also rewired the GPS to the Skyview. Specfically, I needed to patch in the GPS XMIT line to the ELT GPS receive line. While I was working with it, I cleaned up some of my less than professional connections from my first try at the GPS wiring.
