Here is the power Distribution it may help this is for 78

Ok friday afternoon update. I pulled all of the wires from the starter or solenoid and dis an ohm test and yes one of the red pwr wires with a inline fuse was shot, picked up a new inline fuse and reattached the wires and the lights went on and yes we have ignition! Still a little confused about the difference in wiring from your comments and the schematics? Main battery red plus wire and the two inline fused red wires on one post at the starter, The other red pwr wire must be on the solenoid And the black wire from the starter wiring harness that all 3 wires are attached to is hooked to a screw/bolt in fron of the starter...the black battery ground is attached to the frame beside the starter. Anyway for now back to where I was. Still no blower unless I hot wire it from the blower relay, And now have some voltage to the harness plug that attaches to the resister blower and some pwr that was not there before.but no blower so resister maybe bad! Also the vents are not opening and closing as per position of the ac.htr control so either it's bad or the vac lines are not right....I set them up as per your posts but different doors then the ones are opening... I will go over everything and post a pic to see if anything stands out... The plenum door is always open will not close..and inside ht door is open in vent? The vac valve sitting on top of the htr core does not move is not the white top to spring out and in? Ok going away again so the vette sits unsolved this weekend. Thanks to all for your pics and help, just need to get vac lines working and blower and then the dash if I can remember it all.
