here you go ... looks like COM1 "High" goes to pin 9 and COM1 "Low" ends up at pin 1 which is ground.

I'm installing a KX-155 as Comm 1 with a PMA 6000 M/S audio panel in my T-18. The KX-155 has both Comm and Nav Audio Hi and Audio Lo outputs. Does anyone know if the Audio Lo outputs go to ground or to somewhere else? The audio panel does not have Hi and Lo inputs, it just has Comm and Nav 500 ohm inputs. |

Low is equivalent to ground on the audio panel's side ... I'll get you a pin out. |

Anyone have a source for pitot and static manifolds? All of the "T's" and tubes under the dash are getting a bit cumbersome. My airspeed indicator, autopilot, and now my transponder all need pitot pressure, while the airspeed, VVI, altimeter, autopilot, and transponder all need connected to the static source. I suppose I could make a couple, but I needn't reinvent the wheel. |

Bob, I used 1/4" nylon tube and the quick disconnect fittings from SteinAir https://www.steinair.com/product-category/pitot-static/ Two other suppliers of these fittings: http://www.MettleAir.com and http://www.pneumaticplus.com The backside of my panel, the red is pitot and the white is static.  enjoy |

Bruce, is your static port routed to you panel or is that your alternate static port? |

I have an alternate static port on the panel, it's a pneumatic switch, looks like a normal toggle switch from the front, got it from Stein https://www.steinair.com/product/pitot-static-toggle-switch/. My normal static ports are on the aft fuselage. |

I bought my tubing and push connectors at the local hardware store. |
