Hi, I am confused about how to install my new flytrex live 3G in my P2. It's already got an IOSD mini and ImmersionRC transmitter. I have the basic P2 Flytrex connector that interrupts the GPS cable and needs power soldered. Question is, where do I solder? All the flying power cables were soldered together when I installed the IOSD mini etc. Would it be best to get the Flytrex Live 3G Can-BUS adapter instead? ( https://www.firstpersonview.co.uk/cables/flytrex-live-3g-can-bus-adapter-vision ) I'd like to avoid more soldering if I can help it. I am confused though as it says the CANBUS adapter is only for the P2 vision. Help please! Thanks.
