Removed unused wires from the SV-EMS harness. I also removed wires from the harness that will be replaced by wires that are already routed to the EMS from other equipment.
Temporarily connected the Garmin G5 to the battery and turned it on. Played around with the various screens. It seems to work fine.
Built the harness for the G5 and pinned in the power wire that had been run previously. Connected the harness to the G5 and routed the wires.
Discovered that the two wires for the serial connection from the VP-X pro to the Skyview display were connected to J2- 20 and 22 on the VP-X rather than J1-20 and 22 as specified. Depinned the connector and moved them to J1.
Installed a ground wire for the VP-X Pro serial to Sky view connection.
Spent (more) time moving the remaining loose wires around trying to work out the best options for the remaining wire routings.
