This is how I set up for nose gear door air switcht close the door. This photo is Super Hornet photo. The Viper Jet set up the same way.

The gear door aircylinder down side Tee off from the retract down side.
For up. Tee off from retract up and go to the air swicth. When the wheels go up and hit the switch to close the door.
I use gear door offset hinges to set up this.

Maybe the photos can explain better than my Vietenglish.
