I wanted the pilot grip to be removalable in case buttons need to be replaced. So I adopted the same idea from the co-pilot side. There is enough loop of wire at the bottom to pull the grip up and off the stick about 2 inches which is plenty of room for a molex connector.
So I got a 9 pin 062 connector. It is square and easily fits inside the stick.
I installed the connector. I also installed nylon wire mesh on the whole wire runs from the grip, down the stick around the floor until the get to the forward cabin. This will help for chaffing. Probably not necessary because the mil spec wire coating is sufficient, but this is extra quality.
