Real yoke wiring

[Gallie]

I recently acquired a pair of real 737/727 yokes with its original color coded wiring.

Is there anybody out there who knows the these color codes
I know i am not the first person to wire original yokes...

Thanks,

Mike

The best thing to do is put a multimeter across the wires and press the buttons and map them out yourself, should only take a few minutes.

I tried Trevors approach first, but got tricked with the trimswitches doing dubble actions.
I got it right after looking at the diagram on the trimswitch housing. Colors and wieringdiagram is printed on there.
I can check my colors if you haven't found out already, and unscrewing to look for yourself will only take a few minutes. I have wired up the buttons only.

The AP release button is normally closed in case you were wondering. This allows the AP head to receive continous power to the solenoid switches once requirements have been met for AP engagement.
