Plans: 1. Mount the ECU module to the airframe. Status: 90% complete. A mounting surface plate was created where the ECU module naturally ends. Recall that the harness is prefabricated so I need to use it as-built. It is rather long, so the excess cable takes a long path around the fuel spout. There are also some additional cable interfaces that need to be terminated somehow. I am thinking this plate might work for that as well.
