I have to find the input resistance; the resistance between A and B. I think it's Thevinin's theroem, however it is already an open circuit and there are no voltage sources and I can't combine the resistors to make an equivalent. So what do I do

Edit: Am I suppose to remove the 4 ohm resistor connecting the two parallels, and find the equivalent resistance of those two and then add back the 4 as if it were in series?....so the final answer is 16/3 ohm? or is that wrong?
