odd dash lighting issue

[gramps77]

Does the dash wiring somehow get power via the same harness as the radio? About a week ago I pulled the old AM radio and didnt drive it or start it since then. Now, I have no dash lights and the temp gauge and alt gauge dont work. Nor does the fuel gauge. Im hoping its simply because I dont have the radio hooked up. Also, the turn signal indicators in the dash stay on now but will flash when I use the signal. I dont have a diagram to go through and verify, thanks for any help
