I decided on a sealed automotive type pinned electrical connector to join the outer panel bundles to the center section bundle . Available thru A/C spruce.
Pins were crimped and soldered .
Note : I plan on adding an ispection hole immediatley below the connector for potential matainance issued and wing assembly . The addition of the inspection hole will also allow access to secure the wiring after wing assembly and prevent or protect the # 1 wing rib from damage due to wire(s) rubbing or vibration chafing . Chafing material shall also be placed on the rib areas were this might occur
