electrical question.

I’m looking for a keyed power source, from either of the pictured stock connectors.

Without knowing AT LEAST what year Bronco you're working on, it's hard to give you good advice. The more we know about the truck, the more-relevant our suggestions can be. Put all the details into your signature so we can review them with each reply.

There are very few keyed circuits available, and their suitability for modification depends on exactly what you want to splice into them. So again: the more you tell us, the better responses you'll get.

Also if you are looking for key on only or key on and start.

And will the stock connectors still be doing their original jobs? Or are they currently unused for anything else?

I agree with the others, and if you're going to be using either of these to power your aux fuse panel, you'll want them to trigger a relay instead. Maybe that's what you have planned, but it deserves mentioning.
And do you want them hot in ACC as well?

In the first pic the red 3-wire connector should have a Red w/green wire. This is the resistor wire for the coil. It might show 12v initially and under very little load (such as a test lamp or volt-meter) but will soon go down to nearer 9v instead.
But it's hot in ON and START only. Not in ACC. It can be used to trigger a relay.

The round tubular connector is possibly for the Anti-Dieseling Solenoid, which you obviously no longer have use for. It is 12v in ON, but not sure about ACC

The Green w/red wire in your second pic was from the old regulator and is also 12v in ON and START, but not ACC. If you're running a modern alternator this is a good source for a computer signal.

If you want something that is hot when the key is in the ON and ACC positions, but not in START, check the round connector in the first pic.

Okay sorry I have a 71 bronco, the plugs on the fire wall will be used so the Gages work. I am looking for a 12v supply while in the start and run position required by the pro flo 4 system.
Thanks. I should have been more specific with my original post.

Put it in your SIGNATURE so we can always see it, without digging back through your posts, or asking each time.

Will the sniper be controlling the ignition too? If so then you won't need the Red w/green wire anymore, so this can be used for your purpose if you install a relay in between. (because it's not 12v all the time)

I am looking for a 12v supply while in the start and run position required by the pro flo 4 system.

Normally the only two wires on the truck that have what you need are the previously mentioned Red w/green wire, and the Green w/red wire over on the passenger side for the old regulator.

But you can also test that round connector (is it a Black w/blue, or Blue w/black wire by any chance?) and see if it has power in START also.
I've never tested it and forget where it gets it's power.
