I want to make a phototransistor cable for my S110 to attach infront of its red eye LED light and connecting it to pixhawk in order to imporve the geotagging process. But I am fairly new with electronic, wiring and soldering stuff.

Thus I need help and guidance on how to properly make one. I want to know is this the right connection for me to make the cable.

Any help is really appreciated. Thank you.
