Today, I started wiring the back up engine gauges. The primary gauges are part of the Blue Mountain EFIS 1. I decided to daisy chain the power and ground leads here to keep it simple. Both ends of the daisy chain are connected to the main bus or the ground bus accordingly, so if a wire breaks, all the gauges downstream/upstream won’t go out. If you’re wondering about the red/black wires going forward from each gauge, I stuffed them through the mounting holes temporarily to get ’em out of the way!

Here’s a shot of the grounding block on the firewall. Starting to fill up. Do I really think I’ll be needing all those tabs?

Starting to get some wires going to the fuse panel here too. You can see here where I mounted the main bus/e-bus diode. The fuse panel acts like a heatsink. I’ve tried running this to see how hot it gets. I put heatsink compound between it and the panel. Doesn’t really get hot when mounted, but it did when free floating.

Just a shot between the panel and sub-panel showing what’s going on…. I’m trying to keep it tidy while I’m doing this. I should take a picture of Cameron’s wiring!
