The below image shows the pinout of the connector that plugs into your gimbal. If you want 2 axis control you will need to create a connector to plug into the white socket. If your happy with just 1 axis of control you can use the pins to the left of this plug allowing you use the gimbal without modifying the camera cable. I installed a Geocalla 4D-3D gimbal which is not as good as the stock gimbal however it works and was cheap (I crashed and broke the stock gimbal!!!!).
