I see this is an older thread but I am in desperate need of help and no one local knows anything about eps in projects. I have a 68 F100 that I installed 09 Prius set up and wired accordingly. The truck has not been started yet as it has been receiving several mods. My problem is with the truck on stands, I can turn the wheels back and forth by hand and the eps box turns but once inside, the steering wheel will not move past a half inch. It is like one side freely moves and the other is stuck solid. I can't start the truck yet but with the key on I hear the eps box sound up but still does nothing inside. Any and all help greatly appreciated! I have a video of it but not sure how to attach here. I could email if interested. Thanks
