has anyone have an idea on how to do the all high mode on a NNBS silverado? ive done it on a 04. Any ideas?

The NBS Silverados already do this from the factory...

yes they do but i meant with the fog lights. the highs and lows are both on but turns your fogs off

I haven't gotten to play with e NBS so I'm unfamiliar on how their underhood fuse box is. But if its set-up like the others, just run a diode from the activation prong of the High Beam relay to the activation prong of the Fog Light Relay...
