Powered EFIS and iBox through the electronic circuit breaker (ECB). Several dip-switch profiles were tried along with grounding ECB circuits 1 and 2. bridging the ribbon cable outputs did not activate the breaker(s) every time the power was cycled. Build a wiring harness with CAN bus connections and ground with a DB9 and to enable programming the ECB. Was able to program the EBC from the EFIS, setting profile 31, breaker name, trip time, trip current, and startup state.
