I need to power a GPS off the radio power connector on my '75 Ranchero GT, my stereo/receiver being long gone. The Ford radio power plug mates to a 3.5 mm banana plug. This is the power plug: https://www.supermotors.net/getfile/1170774/fullsize/img_4293.jpeg I had to buy three with 6" leads just to find one. Obviously I need only one. Anyone else need one just send me a PM.
