GNC355 to Signtronics

[rexbaker]

Has anyone wired a GNC 355 to a sigtronics intercom? Trying to correlate the two wiring diagrams together. The sigtronics harness has no shield but the 355 install manual has the out puts as two strand or 3 strand shielded... Do the audio lows need to be wired to a ground or simply not wired?

If you have two boxes, one with the other without, an ‘audio lo’, wire audio lo on one box to ground on the other. Attach the shield to ground at one end only, usually the intercom.
