With the Advanced avionics I'm using the flap position indicator will not work. Need to order a different type and also needed to change a push button on the Infinity stick grips to a toggle. Ordered the toggle switches and began changing them out. Opened up the stick grip to find a mass of wires and several buttons to choose from for removal. I decided to go with the manufacturer recommendation to put the flap toggle switch in the #3 position. (Upper left on right grip and vice versa on the left grip). Removed the button and clipped the wires. Stripped and resoldered the wires to the toggle. Soldered the connections per the wiring diagram in the instructions, but not sure of correct orientation. Will wait to do the other grip until I hear from the manufacturer.
