I'm building a Four engine aircraft with retractable landing gear with doors and I want to put a limit switch between the door servo and the retracts.
Can I just use the red wire on the servo?

If you put a limit switch in series with a servo wire, how will you get the servo to move again when you want it to?
Maybe you need a gear door sequencer.

I built an OV-10 that used pneumatic retracts. The nose wheel doors and retract valve were on a y harness. The nose wheel door servo positive wire went through a micro switch. I set the switch to complete the positive lead circuit to the nose wheel servo when the switch was closed by the nose wheel tire. Retract switch in the up position would activate the retract valve servo raising the retracts, since the micro switch was open the nose wheel door servos did not get power and the doors stayed open. Once the nose wheel retracted completely closing the micro switch the nose wheel door servo would get power and close the doors. The pneumatic gear had restrictors so there was a delay that would allow the nose wheel doors to open fully before the air pressure lowered the nose wheel tire. Long explanation but the answer is yes.

Thanks pkoury,
That's kind of what I had in mind. I'll assume the red wire is the positive.
