HUGE THANK YOU TO @trigavionics Without you guys we couldn't have done this part of the build AND have a such tiny transponder with everything we need! Follow along as we run wires through our 1939 J3 Cub with the fabric still on. A lot of the ground work was done when we installed the radio, but we still had to make some custom brackets to mount the GPS and Transponder antennas. Lets just say, I'm happy with my work.
