Starter clicks using the key, engine starts by jumpering the relay

So here is what we know.

1. No wiring changes till after the problem came to a head.
2. With right turn signal on the key will crank the engine and start but it won't stay running.

One addition to #2 - the engine will start and stay running now. But still only with either the left or right turn signal engaged. Once the engine is running, I can disengage the turn signal and the engine will stay running.

Now we know the following is good

1. The starter works fine.
2. The starter solenoid works fine
3. The starter relay works fine
4. The NSS cir works fine.

Problem...

1. The key should not require the turn signal to be on to start.
2. With the key in the run position and the turn signal on there is no power to the ignition.

I suspect that with the previous "giggle wires under the dash" allowed the engine to start that there are bad connections and maybe shorted wires under there.

That is my hunch, that the problem is somewhere in or near the bulkhead. But then again, I’m the one asking for help here, haha.

I don’t know if this is related, but I’ve blown a couple fuses recently: the stop lamp fuse and the emergency flasher fuse. I replaced them and they haven’t blown since. I also don’t have any tail lights when the headlights are on. Brake lights, no tail lights. I think I may just need to rip all of the wiring out and start fresh, as mentioned before.
