question regarding the factory fog light harness.
 

okay so i just built and installed my new fog light set up. and im curious is there a wire in that harness that is just a blank wire. no hooked up to anything that i could tap into that would basically be a wire i could use that is allready through the fire wall and can use it on the other side? does that make sense? because the LED fogs are grounded... and i have a long power wire that i need to run through the firewall then connect to my switch then to the secondary fuze box i have installed thats isolated and hooked to the battery. i would rather not run this wire through the firewall if i can help it. it would be much easier to use a wire from the fog light harness since thats not being used nor will it.

here are my fogs:

mounted them by machined recesed straigh slots in the billet grill so they face perfectly forward:

and i lit them up by attaching the wire straight to the battery:
