Fs-ia6b problem with connecting to sp racing f3 in betaflight

I connected fs-ia6b to sp racing f3 like this, joy is connected with receiver, all settings in betaflight are set up, but when i try to check in betaflight “receiver” nothing happens? Any suggenstions? I will change theese wires in next week to correct…

dont have that receiver but never had much joy using io2 to connect sbus/ibus i use uart3 and solder direct to pads.
also noticr you have something connect uart1, whats connected because if it powered when pluging usb in connection to gui will be flaky at best.
if all else fails use the ppm pad on the bottom of spracing with receiver in ppm mode.
