It doesn’t appear that you have the bind plug in the receiver. The bind plug is a small black wire that loops back on itself. It just connects the two outside pins together. You have to put that on first in order for the receiver to go into bind mode.
Also, on your transmitter, that 12v power supply appears to be a battery charger. You might have to unplug that before it will bind, but I don’t know that.
After you bind, the red lights should turn solid red, so if they’re blinking, you haven’t bound yet, probably because you don’t have the bind plug in.
