trex 450 and kds 800 gyro

[loz]

i have bought a second hand 450 and have bound it to my tx, but rudder servo/gyro isnt responding, lights are flickering a bit so im guessing its gonna be something ive not setup properly, i have looked at manual for it and it all seems to be on correct settings does anyone have any idea what could be wrong?

looks like just plugs in wrong places on rx
