Made up the coaxial cable for the Icom comm. radio and rand it from the instrument panel, under the right seat and up the right channel to the center to all the antennal to be installed in that location. Well, now I needed to remove the cover I put over the remote compass to make room for the OAT. After a lot of figuring and fitting in a small space, I was able to install the OAT in the cover, make all of the necessary wiring connections, and reinstall the cover. I riveted in place for the last time, I hope.
