Fabricated optional aux audio jack using Radio Shack RS 274 249 jack. Soldered inline, two 47K ohm resistors. Had a little bit of trouble with the small terminals on the jack - they are flimsy and easily break. I also flamed one of the jacks by letting the wire get too hot! Finally got the jack put together and integrated with the ES-00147 RH heatset jack harness. Installed the headset jack harness and secured. Ensure that there was no continuity between headset jack nuts and ground. Also, verified continuity between the aux audio jack body and ground. (page 31B-17, steps 2 through 6). Page 31B-17 is complete.
