Ignition help needed (stumped)

Hello everyone, looking for some insight. I have a 75 Space Duster 318 i recently aquired and the issue is this. It will not start off they key, infact, key does nothing at the moment. Previous ownser (s) have jumped power to the ballast resistor from power wire off bulkhead . This still does nothing for the key but car can be jumped via starter relay and runs fine. But cannot shut off unless 1 of the jumpers are pulled off. Also no power to lights gauges or anything except oil light when jumper is attached. Gonna pull dash today as have power going into bulkhead red wire but nothing coming back out of bulkhead. pic added if I'm not making any sense. Thanks for any help or suggestions. I should add that the jumper is on both upper post jumped to power going into bulkhead
