I'm helping a friend who purchased an RV8 that has no known electrical documentation. The original builder is deceased. I came across this small black box that has 4 wires and surgical tubing attached. It has no markings on the visible surfaces. I have not yet tried to trace the wiring and where the tubing ends up is not apparent.
If you happen to know what is it let me know.
Thanks in advance.
