Here is my relay tray. Sits under the fwd seat pan and is removable. Holds my smoke relay, WigWag relay, panel dimmer, and trim relays and speed controls. Plate nuts make it easy to remove. Molex connectors make it easy to troubleshoot
You have seen this before on other RV-8's. A simple drop door with access to the fuse panel and wiring.
Here is my switches and breakers and legends. All made with a Brother P-Touch label makes. One of life's little gems. The blue tape is keeping me from scratching the paint.
