    Real Boeing 737 yoke handle wiring

    Hi all,
    I have just wired my pair of real Boeing yokes and thought I would share the wiring code for anyone else who is going to install real yokes. The real Boeing wiring harness contains 14 wires, I found that two were redundant or spare.

    1 ELEVATOR TRIM ROCKER SWITCHES (Both switches must be operated together to work)
    Boeing wiring harness colors
    White/Red = Common
    White/Orange = Trim "Down"
    White/Black/Orange = Trim "Up"
    White/Violet = Makes with White/Red - both directions *Not used in my sim*

    2 PTT ROCKER SWITCH
    Boeing wiring harness colors
    White/Black/Brown = Common
    White/Grey = Intercom (Bottom trigger)
    White/Red/Black = Mic (Top trigger)

    3 AUTOPILOT DISENGAGE PUSH BUTTON (This button has 3 pairs of contacts)
    Boeing wiring harness colors
    Pair 1 - White/Blue + White/Black/Yellow = A/P Disengage (Normally OPEN switch)
    Pair 2 - White/Yellow + White/Green = Normally CLOSED switch *Not assigned in my sim*
    Pair 3 - White/Black/Green + White/Brown = Normally CLOSED switch *Not assigned in my sim*

    Cheers, Gwyn

    This is great info and will help me too. Perhaps the other two pins are for the light in the trip number reminder (if that's what it's called)?

    Thanks!
