What do you guys use for your electrical wiring between instruments and such?
Most of the photos I've seen show wire that's quite thin (makes sense for weight savings) - on the order of phone-jack wire or Cat5.... I'm assuming RG58/U for antenna wire... Is there any issue with using Cat5 ethernet cable for making data (say, encoder -> transponder) and audio-panel hookups, and with, say, 18ga automotive wire for 14v power (to/from circuit breakers)? Is there any real advantage to teflon-coated aircraft wire over more common twisted-pair varieties? I assume that power and data connections should be routed away from each other... The gear I bought has it's 'internal' harnesses intact (eg, between navcom and obs, or between the various EFIS components), so most of my wiring will be limited to audio and power. The only 2 devices I need to connect for data transmission are the transponder and the EFIS (which has an internal grey-code encoder)...
