can someone identify this circuit (picture included)

[BOTTLEDZ28]

1998 2 door tahoe 4x4. I need to know what these terminals (circuit) is for. Im referring to the NAT and BLK empty terminals. BLK is hot at all times while NAT is hot in RUN only. I'm looking for a location to hook up a switched 12V wire for fog lights. This is the only location on the truck that has a spare terminal that is NOT hot at all times.

This circuit block is under the dash just to the right of the parking brake.

This is from alldata for a 1998 K1500, maybe it will help.

THANK YOU SO MUCH. I wish I had a print out of all the diagrams for my truck. Stuff comes in so handy when doing work.

That would be a good place to pull fire from to use for your trigger wire on a fog light relay, but don't hook the load here, it'll burn up your ignition switch.

It looks like there is a spot for a factory fog light relay in the lower left corner.

Would he be able to duplicate a factory setup from a 2000 Limited or Z71 Tahoe instead?
