I have been working on cleaning up the wiring mess I created for myself. I call it 10 lbs of poop in a 2 lb bag. But realistically, if you add up the weight of all the avionics and wiring its probably closer to 30 lbs all in. Not that I have weighed it.
Having a super light engine, my plan was to move as much forward as possible to help offset the weight. Between the panel and the firewall are the following components:
- 2X 10.3" displays
- Backup EFIS
- Prop controller
- Advanced ACM
- UL ECU, boost controller and aux box
- COM radio
- Room for IFR GPS and NAV/COM
- Avionics backup battery
- Header tank
- Audio panel
- EMS
- ADSB receiver
- Hall effect sensor
- GPS 2020 receiver
- Skyview expansion bus
- And all the normal 'stuff'.
Add all that together, and its 10 lbs of poop in a 2 lb bag.

The relatively clean panel hides the mayhem that hides behind it.
The GOOD news is everything works. All the avionics are connected, the ECU is talking to the EMS, all the controls on the sticks do what they are supposed to. Radio / audio panel / audio all works. Servos are talking to the system. Prop controller has power and just needs connection to the hub. All of the lights (nav, strobes, taxi, landing, panel, overhead) all work. Pitot heat is ready to go once the wings are attached and wiring finished. ECU indicator lights. Circuits for the engine and transfer pumps. It all works. Yay me.
It's not 'pretty' like I hoped it would be. But to move the weight forward and contain it all between the panel and firewall is an extreme challenge. If I could get rid of the ACM and use CANbus only, it would be way neater - but that is not the path I chose.
Once the weather dries out a bit, the engine will come off and the real firewall will go in, and then I can finish up the firewall forward wiring (fuel pumps, batteries, relays, shunt sense wires, prop controller, etc)
I am tired of wiring, and look forward to building parts again (which is totally ironic).
Merry Christmas.
