I will be ordering an EFI in a month or two, but I have spent more than 6 months trying to figure out how I want to wire it. My "dream" was to use an automotive relay and fuse panel. That is still my long term goal that may not be attained. My second choice was an aftermarket panel, which I now possess and am wiring up. Hopefully in the next few months I will have the time to figure out how to create a professional looking electrical system on a PC. Right now, not so much.
I am using a "Severe Service Vehicle" relay panel. Meant for construction equipment, off road vehicles, etc. All primary circuits will operate off of SPDT terminal 87A in their primary mode. NO relay operation required to run the engine. I will have a bank of micro switches to energize the relay coil and switch the relay to terminal 87, which will shut off the circuit. These switches will allow me to shut off fuel pump 1 or 2, ignition 1 or 2, or alt 1 or 2. If any or all of these switches, or their power source fail, no problem. The engine runs. They exist to check the function of the backup, or select the backup. Each function has its own circuit. No A/B switches.
The panel uses Delphi sealed connectors, and the whole panel is IP 66 or 67 for moisture and vibration. it is a little heavier than I would like at 3 pounds. But compared to a bunch of bus bars, etc, it might be a push. Maybe 550 to 600 bucks with all connectors and wire.
The power to the panel will comply with one of Nuckols wiring schemes.
Hopefully I get automotive reliability, with the ability to test backup functions, or switch to the backup. Like I said I would prefer to use a stock auto panel, but I haven't found one that I could easily switch functions "off" to check the backup.
