8FD40U display

So I have no power to my display. Unit has the combo meter. I checked all fuses and relays in circuit. Tested continuity. Checked grounds. All tests fine. Now if I just the relay that's in the dash the dash works. If I jump the fuse direct to battery display works. Otherwise I cannot for the life of me get the thing to work. Connectors all look fine. No wiggling or cutting in and out. I've swapped relays and fuses to be sure as well. No change. Only works when I hook up direct power. Other than the display not working the unit operates fine. Could this possibly be the ignition or headlight switch.
