No electric power in the dash

I have recently bought the truck from auction. It has no power in the dash when I insert the key in the ignition no lights nothing. But the wipers work when I put the key. There is power in the cigarette lighter and the tilt steering function works and the brake and accelerator height adjustment system works. I have checked fuse boxes and relays with multimeter they seem fine. When truck is in park and the battery connected key doesn't come out of ignition it only comes out when I disconnect the battery.
