Barracuda Turn signal indicators inop on dash cluster

Well as an update I'm getting power for the turn signal indicators on the harness at the dash cluster. The left signal comes from the three pin the right signal comes from the 8 pin
Yet neither one is working on the cluster. I tried switching bulbs and switching the black plastic holders. Still no luck. These are new circuit boards. What are the odds that they would both be defective? I can't think of anything else that would cause it not to work? I'd appreciate any ideas I'm at a loss. Thanks again!
